Hello -- I looked at the coins available from the dealer you mentioned. Most of the modern coins are genuine but half of the old coins (cast coins) are fake. One clue -- he has at least three 3-hole spade coins, starting at $15. These are the rarest of Chinese ancient coins. Coins from about 25 different places are known -- every one of them extremely rare, some known from only a single example. Genuine examples rarely ever show up, when they do, they start at US $10,000. Two of the pieces he has are from the same mold; only the patina is different. -- Bruce W. Smith
