I agree , i bought that coin from a
German auction house. The coin is extremly crude for it to be a 12th century imitation but the
monogram is very similar to the original.
Most imitations are light
weight and created in the 13th century. In this case it is heavier, 2.6 gm and larger 24mm.
Maybe the similarities are simply a coincidence, after all the coin did not commonly circulate in
Asia Minor.
