24-23 mm. 5.82 grams. 23 mm. 8.82 grams. The first is Sear 1783 (DOC III.II Nicephorus II 7) and the second Sear 1782 (DOC 8). The difference is on the obverses; the reverse legends are the same. +ҺICHF/ЄҺΘЄWbA/SILЄVSRW/MAIWҺ The faces are very similar. However, the second has the emperor dressed in a loros (the shirt with big dots), holding a labarum (a staff with a squarish head) and holding a globus cruciger (a globe with a cross on it). The first has the emperor with a loros but also an additional garment over it ornamented with pearls, holding a long cross (instead of a standard), and the globe has a trefoil ornament on it, not a cross. I'd love to have better examples to show you, but they are hard to come by. Even Sear's plate coin for 1783 is only a bit better (He does not have a plate coin for 1782). The obverse legend is supposed to be: ҺICFR B-ASIL RW (first coin, Sear 1783) and on the second, ҺICFR BASIL ROW. DOC has those legends too. I think I see more letters than that on the top coin's left side, but these are usually overstruck and some of the extra letters (if there are any) may be from an undertype. I'd love to see other folles of Nicephorus II, or anything related.
