Anastasius I performed a major currency reform aiming to ressurect the colapsed bronze coinage system by introducing new
denominations: 40 nummia (
follis), 20 nummia (
half-follis), 10 nummia (1/4
follis) and 5 nummia (1/8
follis). He started with small module folles but later he introduced heavier issues. The same policy was conducted by
Justin I.
Justinianus, tried to make the best of the huge imperial treasury inherited from
his predecessors by launching an offensive westwards in order to reconquer the former
roman territories in western Europe and northern
Africa. He introduced a huge copper
follis along with a
new style, the facing
bust and the regnal numerals on the
obverse.
His victories were not to last and as the treasury was smaller he decided to reduce the size of the
follis gradually.
This policy was continued by
his nephew
Justin II, a period of inflation with many coins on the market and of smaller size. The inovation is the presence of the emperor and empress enthroned on the
obverse.
During the reign of
Tiberius II, the
follis regained some
weight and a new stile with uncial
denomination letters on the
obverse and sometimes latin instead of greek numerals. Also the emperor made extensive use of the consular
type, with consular robe,
eagle tipped
scepter and
mappa.
Tiberius was co-emperor from 575 so
his dating as sole ruler starts from year 4.
Maurice's folles
had the same
weight with the half-folles from the first period of Justinian after the reform (538-542).
Phocas the usurper of
Maurice also uses latin numerals and an image with
his wife Leontia on some issues. A
good part of
his early coins are restruck over
Maurice's coins.
Heraclius uses many
types of representations on the
obverse with
his wife and two sons. He opens some exotic mints at Alexandretta, Seleucia, Isaura or
Cyprus in the first years. The coins become more and more small as the empire loses the possesions reconquered by Justinianus and also the Eastern
part of the Empire. The
Byzantine Empire becomes a greek state.
His issues are sometimes
overstruck on earlier bronze from Phocas or
Maurice.
Other general features:
-gold coins are more common than before during the
roman period.
-silver is
scarce even
rare, only ceremonial coins being issued during the sixth c.
Heraclius introduces a new silver
denomination, the
hexagram.
Below are some links leading to coin pictures from the period.
