Two weeks ago, I bought several coins as copies. They have not 揅OPY?marks and have the weight from 19.19 to 20.31 gms. As they are crownsized, they are obviously counterfeits. However, they look very good and can be presenting distantly as silver. They have grey patina; the ring test for inexperienced ear is thin and silver-like.

The main feature, besides the weight, distinguishing these copies from the genuine ones is a randomly shifted interposition of obverse and reverse. I tried to display that in pictures.

I think, these counterfeits are made in China, which has a powerful industrial potential of counterfeiting. So,

Seated Liberty dollar of 1879

Eik dollar of 1971

Peso of Mexico of 1839 (!)

This noticeable fake looks absolutely like un peso, but it dated with the year of 8 reales.

Peso of Guatemala of 1894

10 rupees of 1972

Unfortunately, the interposition can easily be eliminated by a picture manager.

Happy bidding,
Alex
