The opening as it read in 2005

This is an article about the Roman coin; for an article about the French bicycle manuafacturer, see Follis A follis of Galerius as caesar The follis (plural folles ) was a large bronze coin introduced in about 294 with the coinage reform of Diocletian . It weighed about 10 grams and was about 4% silver, mostly as a thin layer on the surface. The word follis means bag and there is evidence that this term was used in antiquity for a sealed bag containing a specific amount of coins. The follis of Diocletian, despite efforts to enforce prices with the Edict on Maximum Prices ( 301 ), was revalued and reduced. By the time of Constantine , the follis was smaller and barely contained any silver. A series of Constantinian bronzes was introduced in the mid-4th century, although the specific denominations are unclear and debated by historians and numismatists. The follis was reintroduced as a large bronze coin (40 nummi) in 498 , with the coinage reform of Anastasius , which included a series of bronze denominations with their values marked in Greek numerals . The fals (a corruption of follis ) was a bronze coin issued by the Umayyad and Abbasid caliphates beginning in the late 7th century , initially as imitations of the Byzantine follis.1
