The original copper coinage was weight-based, and was related to the Roman pound, the libra , which was about g. The basic copper coin, the as , was to weigh 1 Roman pound. This was a large cast coin, and subdivisions of the as were used.
The "pound" libra , etc. Denarius first struck. According to Pliny, it was established that the denarius should be given in exchange for ten pounds of bronze, the quinarius for five pounds, and the sestertius for two-and-a-half.
But when the as was reduced in weight to one ounce, the denarius became equivalent to 16 asses , the quinarius to eight, and the sestertius to four; although they retained their original names. It also appears, from Pliny and other writers, that the ancient libra was equivalent to 84 denarii. Retariffed to equal 16 asses due to the decrease in weight of the as. Death of Julius Caesar, who set the denarius at 3. Legionary professional soldier pay was doubled to denarii per year. Tiberius slightly improved the fineness as he gathered his infamous hoard of million denarii.
This more closely matched the Greek drachma. In AD 64, Nero reduced the standard of the aureus to 45 to the Roman pound 7. He also lowered the denarius to Successive emperors lowered the fineness of the denarius ; in Commodus reduced its weight by one-eighth to to the pound. Several emperors — steadily debased the denarius from a standard of In Caracalla reduced the weight of the aureus from 45 to 50 to the Roman pound.
They also coined the aes from a bronze alloy with a heavy lead admixture, and discontinued fractional denominations below the as. In Caracalla introduced the antoninianus 5. The coin invariably carried the radiate imperial portrait. Elagabalus demonetized the coin in , but the senatorial emperors Pupienus and Balbinus in revived the antoninianus as the principal silver denomination which successive emperors reduced to a less intrinsically valuable billon coin 2. In , the emperor Aurelian reformed the currency and his denominations remained in use until the great recoinage of Diocletian in The aureus minted at 50 or 60 to the Roman pound was exchanged at rates of to 1, denarii , equivalent to to aurelianiani.
Rare fractions of billion [ clarification needed ] denarii , and of bronze sestertii and asses , were also coined. At the same time, Aurelian reorganized the provincial mint at Alexandria, and he minted an improved Alexandrine tetradrachmon that might [ clarification needed ] have been tariffed at par with the aurelianianus.
Pepin the Short r. So a single coin contained 21 grains of silver. Originally the pound was a weight of silver rather than a coin, and from a pound of pure silver pennies were struck. The Carolingian Reform restored the silver content of the penny that was already in circulation and was the direct descendant of the Roman denarius. The shilling was equivalent to the solidus , the money of account that prevailed in Europe before the Carolingian Reform; it originated from the Byzantine gold coin that was the foundation of the international monetary system for more than years.
Debts contracted before the Carolingian Reform were defined in solidi. For three centuries following the Carolingian Reform, the only coin minted in Europe was the silver penny. Shillings and pounds were units of account used for convenience to express large numbers of pence, not actual coins.
The Carolingian Reform also reduced the number of mints, strengthened royal authority over the mints, and provided for uniform design of coins. All coins bore the ruler's name, initial, or title, signifying royal sanction of the quality of the coins. Charlemagne spread the Carolingian system throughout Western Europe. The Italian lira and the French livre were derived from the Latin word for pound. Until the French Revolution, the unit of account in France was the livre , which equalled 20 sols or sous , each of which in turn equalled 12 deniers.
During the Revolution the franc replaced the livre , and Napoleon's conquest spread the franc to Switzerland and Belgium. The Italian unit of account remained the lira , and in Britain the pound-shilling-penny relationship survived until Even in England the pennies were eventually debased, leaving pennies representing substantially less than a pound of silver, and the pound as a monetary unit became divorced from a pound weight of silver.
After the breakup of the Carolingian Empire pennies debased much faster, particularly in Mediterranean Europe, and in Genoa began minting a silver coin equal to four pennies. Rome, Florence, and Venice followed with coins of denominations greater than a penny, and late in the 12th century Venice minted a silver coin equal to 24 pennies.
By the midth century Florence and Genoa were minting gold coins, effectively ending the reign of the silver penny denier , denarius as the only circulating coin in Europe. Offa , king of Mercia, minted and introduced to England a penny of The penny led to the term "penny weight". The tower pound was abolished in the 16th century. However, pennyweights 24 grains made one troy pound of silver in weight, and the monetary value of pennies also became known as a "pound".
The silver penny remained the primary unit of coinage for about years. Charlemagne new penny with smaller diameter but greater weight. Average weight of 1. The purity of By the 16th century it contained about a third the silver content of a Troy pennyweight of 24 grains. The penny, now struck in bronze, was worth around one-sixth of its value during the Middle Ages.

More coins could be issued for the same amount of silver, leaving more money for the central authorities to spend. Having long enjoyed relative price stability, through a combination of wage increases paid to Roman soldiers, currency debasing and increases in public expenditure, by the end of the second century AD inflation had begun to disrupt the Roman economy. Just as in Venezuela, the negative consequences of this soaring inflation and dwindling confidence in the fiat currency were significant.
The variable rate of exchange meant everyday commercial activity in urban centres became more difficult. It had the equivalent effect of ten pound coins being worth a ten pound note one day and a five pound note the next. Citizens no longer knew the value of their money. Economic activity declined. Like in Venezuela, the breakdown in confidence was compounded by civil unrest. In Rome, the civil war in AD led to a reversal of key currency reforms that had consolidated the mints and stabilised the currency by centralising control.
Centralised monetary control of the currency was lost and manufacturing and trade went into decline. In both cases, soaring inflation, dwindling confidence in government and civil unrest precipitated the collapse of the banking system and, ultimately, economic collapse. These typically rely on decentralised control rather than a central banking system. Its value is ultimately determined by mathematical formula rather than state decree or the value of an underlying commodity.
Nevertheless, in larger Venezuelan cities, such as Caracas, Maracaibo or Valencia street vendors now regularly accept payment with digital coins. Bitcoin, Ether, Dash and Eos are among the most popular. The trend is also spreading to traditional stores. In ancient Rome and Venezuela, however, what is without doubt is that trust destroyed can take a long time to rebuild.
It was not until the end of the 18th century in England that the world again had a currency as trusted as the Roman currency had been, or in such widespread use. How long it will take to rebuild trust in Venezuela is not known.
Whether Venezuelans will be as quick to trust a cryptocurrency with their wealth in the longer term remains to be seen. George Maher is an academic and author.

Could a cryptocurrency revolution have saved the Roman Empire? George Maher.
The deficit spending of later emperors nearly halved the silver value of the coinage. Taxes felt more heavily on conquered peoples in the empire. Romans and Italians were exempted from tribute. One defeated Mark Antony, Augustus reduced the military forces and provided men mostly with the land of the new colonies around the Mediterranean.
In so doing he reinforced the boundaries of the empire, favoured its expansion, and created new important centres for spreading the Roman way of life. He also established a central military treasury and set funds for the legionaries. In order to bind his troops to him he rewarded it with regular compensation, occasional bonus, and promotions. The Roman army could count on the ability of Romans for the heavy infantry but also on the skills of the auxiliary troops, composed by conquered peoples.
This measure also fostered a stricter unification throughout the peoples of empire, spreading the Latin and Roman civilazion in all the colonies. While settling legions throughout the empire, Augustus disposed a special troop, know as the praetorian guard, to defend and protect Italy. Augustus left a legacy of peace and prosperity to the Romans. Internal peace revived Roman patriotism and economic prosperity throughout the empire.
He expanded and reinforced the empire boundaries and reorganized the administration of the colonies. Augustus was also a generous patron of literature and art and, in his final decades, the father figure who provided food, entertainment, and security to Roman people. The "imperial system" he had instituted endured for the next three centuries. For decades, Augustus watched his chosen successors die until only his stepson, Tiberius, remained.
Tiberius AD was a successful general and a fine imperial administrator and left the empire with secure boundaries and a healthy treasure. Caligula AD was the great-nephew of Tiberius and his chosen successor. He abolished the sales tax and sponsored frequent public athletic games and spectacles, but a severe illness transformed him into a vicious tyrant. After his death, by hand of one of his guards, the empire was ruled well by Claudius I ad till his fourth wife Agrippina poisoned him to ensure the throne to her son Nero.
Nero AD , after having murdered both his mother and his wife, ruled with increasing despotic tendencies. He persecuted Christians and blamed them for the blaze that in AD 64 devastated much of Rome. As a result of his lavish behaviour he preferred to give vocal concerts at Greek festivities then caring for the legions , he caused resentment among the neglected legions that eventually led to a series of rebellions throughout the empire. All four Julio-Claudian emperors lived in the shadow of Augustus, and none felt secure on his throne.
Insecurity brought tyranny, which then provoked conspiracies in the Senate and in the palace. Finally, even the army turned away from the dynasty that had created the empire. Civil war returned to Rome as one person after another claimed the throne and marched on the capital. The savage civil war of AD 64, known as the Year of the Four Emperors, concluded with the triumph of Vespasian AD , a plainspoken and practical soldier from the Italian middle class. He placated the rebellions in the eastern provinces, restored the economy, recruited the senators from among western provinces, and ensured the loyalty of the military to the new dynasty he created, the Flavians.
After the brief and extremely popular reign of Titus AD , Domitian AD revealed himself as a tyrant who ruled in a reign of terror that eventually led to his murder. Nerva began the dynasty of the Antonines and was followed by his adopted child, Trajan. Trajan , a distinguished soldier, became one of the most beloved Roman emperors thanks to his numerous conquests Dacia, Arabia, Armenia, and Parthia , his common sense, administrative skill, and genuine human compassion.
He initiated an impressive building program throughout the empire and particularly cared about the social welfare programs, such as the distribution of food to poor children. He displayed a great humanity and tolerance. Also his cousin Hadrian , a passionate travel and a cultured man, excellently administered the empire and created a series of military highways that enabled troops to march quickly toward the walls alongside the empire.
The Hadrian Wall, his most famous building project, stretched across km of Northern England. His successor, Antoninus Pius had a peaceful reign but the inactivity of the legions during his long reign eventually created problems to his successor, Marcus Aurelius , who had to face hard wars against Germanic tribes.
After his fruitful campaigns and successful reign he designated as heir to the throne his son Commodus , who turned out to be a startling change for the romans after the series of good emperors. His neglect towards the business of the empire in favour of his passion for the games caused him the death by strangling and eventually led to first civil war in more than a century.
The five emperors from Nerva to Marcus Aurelius are designated as the "good emperors" because, though the great problems of the empire plague, slavery, wars, religious conflicts , they acted as effective administrators who promoted prosperity, avoided civil wars, respected senators, and supported intellectuals and the arts. With the election of Commodus, in AD, Rome underwent a period of bad leadership that caused a collapse of the political institutions, a weakening of the army, and an economic disaster.
After the death of Commudus, in AD, a civil war between rival claimants to the throne penetrated every corner of the corner and changed all he aspects of Roman life. From to AD Rome was ruled by the Severan dynasty, mostly occupied in pampering the army as to defend the empire's boundaries and to assure the future to their dynasty. But this measure only produced the effect to weaken the defences while inflaming the greed and ambitions of the soldiers.
It became clear that imperial power depended more and more on the army. From to Rome underwent a military anarchy whereas the troops acclaimed numerous emperors who all lasted for a very short period. Civil war and the collapse of the central authority had a very bad effect on all the aspects of Roman life: trade became dangerous, local services deteriorated, imperial funds disappeared and money underwent a terrible devaluation. But the crises particularly damaged the lower classes. The farmers, unable to pay the taxes, had to abandon their lands, provoking the first widespread food shortage in centuries.
The rich freedmen of the early empire disappeared, slavery declined and, except for soldiers, social mobility was impossible. Widespread bitterness, poverty, and growing hatred of authority led to popular revolts in Rome, rural massacres in Africa, and local separatist movements that attempted to break away from the empire entirely.
The brilliant leadership of Diocletian , who ruled from to , rescued the critic situation and restored through important reforms the political and economic system bringing back peace, stability, and prosperity to the Empire. To better control the vastness of the empire, Diocletian instituted the so called tetrarchy, a rule of four that eventually led to the separation of the empire into east and west. This measure had the scope to foster the administration of the empire and guarantee a secure defence of Rome's frontiers.
Besides this historical step, the emperor issued a decree, the famous Edict on Prices, to fix throughout the empire the prices of all the products. Through this economic reform, Diocletian succeeded to restore value to the currency, to control runaway inflation, and to finance the imperial budget. The system ideated by Diocletian collapsed after his voluntary retirement.
The empire was reunited under Constantine , famous for his Edict of Milan , that established toleration of all religions, including Christianity. His religiosity eventually led him to found a new capital, Constantinople , on the site of the ancient Greek city of Byzantium. In so doing, the emperor established Christianity as the favoured religion of the empire. Following Diocletian's example, Constantine greatly increased state control over the lives of Roman citizens. He tried to keep the empire under his own control through a larger army, a central economic planning, and an expanded bureaucracy.
Every aspect of the life, throughout the Roman Empire, was regularized by a rigid control. The enormous complexity of the system led to an inevitable rampant corruption. Theodosius I was the last ruler of the united Roman Empire. At his death, he assigned the eastern portion of the empire to his son Arcadius, and the western portion to his son Honorius.
