IMHO, All of Pocono Penn's coins are genuine. Qing dynasty cash with the same "nien hao" can vary somewhat in diameter depending on the Provencial mint, changing standards, mint master corruption, and other factors. Sandac's coin was from one of the Beijing mints which have the most consistent quality. The second coin is from which mint?
Thank you for the help. Recently. Inside China, ancient cash coins appear to become very desirable collectible items. During last two months, I have checked my junk box which has many cash coins. Here are pictures of eight large size cash coins. I can identify two of the coins in the first raw (left and right). The rest coins are unknown (at least not in my two reference books), may not be genuine. The two coins which is identified in the attached pictures, has some design differences from my coins. Can you comment on them?
