Mexico Un Peso 1901 - A Clear Case Of Casting Specimen?

kerjaluar Welcome to the forum.

The coin is unfortunately heavily scratched making it a "bullion" item at best, in my opinion.

However, on the picture of the edge I see what appear to be at least 12 "split reeds" - that feature always bothers me because it is usually associated with a forgery. The way most split reeds occur is when the coin is edged in a ring die. We have discussed ring dies before, but because you are new - a ring die is a tapered hollow metal die with reeds cut on the inner surface. A stack of counterfeit coins are pushed through the ring die to cut reeds into the edge of the coins. The process causes metal to flow up along the sides of the reeds and curl onto the top. Where these curls meet there is a joint (the split) at the top center of some reeds. This feature is often removed by grinding the edges which leaves another problem (but that is a different issue). By the way, I see no edge grinding evidence. A collared strike does not make reeds with a central split. In a collar the metal flows into the recess just like it flows into the recesses of the die. NO SPLITS.

I was also a bit concerned about the width of the rims and the anomaly under the date. But those could be real as easily as not.

So the coin needs to be tested to make sure it is silver and not a white metal. Have you weighed the coin accurately? If you do own a scale that can weigh to 1/100th gram you should read the threads on specific gravity and test that as well.

Good luck and once again welcome to the forum.
