John II Comnenus, 1118-1143. Tetarteron (Bronze, 21 mm, 3.48 g, 10 h), Constantinopolis, circa 1122-1137. [...]ΠΟ[...]TⲰ[...] John II standing facing, wearing crown and loros, holding scepter cruciger in his right hand and globus cruciger in his left. Rev. + [I]Ⲱ ΔЄCΠΟΤH-C TⲰ ΠΟΡΦVΡ[...] John II standing facing, wearing crown and loros, holding scepter cruciger in his right hand and globus cruciger in his left. DOC 12a. SB 1945. An extremely rare mint error. Flip-over double strike and with minor deposits, otherwise, about very fine.



This coin is a so-called flip-over double strike, meaning that the flan was not removed between two strikes but flipped over, which resulted in the figure of Joh II being fully visible on the reverse.
