Another coin from the same lot. The label reads: AE/Billon Tracey.Constantinople. Emperor atheist.facing hold Labarum & anexikaka. BMC•sword in sheath Rev. Virgin enthroned facing. Double struck & flattened BMC Manuel I. 58 G. Size: 21 x 22 mm Weight: 2 Gmail.72 obv. Inscript. seems to be XECNXT on V. Off flan on l. imitates coins of Manuel BMC•56/57• D.O.pl.25•6/10• I have no idea if this is correct or not. The asking price was $2.00 but it didn’t sell. Again, it cost me $5.30 but I can get my money back in the antique shop on this coin.
Curious. The design copies that of the Latin Type A billon trachy SB 2021 (as the writeup basically says), with the legend roughly DECPiTC, but the coin (or whatever it is) seems to be silver.
