Let me start by saying I know less than my cat about Chinese coinage, so I may be entirely wrong. I research and collect American silver (not coins) in the Federal era. I periodically scan the bay for such under the Coin Silver Antique pages. As might be imagined, there are often coin coins posted there in error. Today a newbie Hong Kong dealer posted 30+ PCGS holdered coins. Out of curiosity, given the large number of US coin forgeries, I looked up, randomly, several of the #s. To my untrained eye, they were not the same coins. I suspect folks here are just as dedicated to outing such things as the posters on the US forum, so someone with knowledge might take a look. I have no interest in any part of this offering, simply trying to spot things as I go.
