I need
help attributing this coin. I purchased it as
Arab-Byzantine but it does not match any of the transitional coin
types in the
Dumbarton Oaks Collection that covers coins issued from 600-700. I reviewed other
Byzantine issues and the only coins I could find with matching observe and
reverse devices were some of the issues of
Constantine X &
Eudocia (1059-1065). However, there is a difference in the size and
weights. My research indicated that
Constantine X coins range from 26-29 mm and 8-12 gms. My coin is 4.2 gms and 21 mm. Also, there are devices (line drawings) on the
obverse and
reverse that look like
monograms from late
Roman coins. Any
help in identifying this coin would be appreciated.
