I purchased a 1893 O Morgan on E-Bay by a Chinese seller. It was so perfect I could not tell it from a good coin. It was when I was placing coins into plastic holders that I found the coin to "thick" to close the holder correctly. A local coin dealer examined it, all sizing, weight, appearance was correct. It apparently was not silver material that caused the coin to be thick for proper weight. Appearance wise it was a darn good fake so I went from having a coin worth hundreds to having a worthless ????????
