mfm, you are thinking as someone with a lot of knowledge on the subject. Most people do not have your level of knowledge and are not going to obtain your level of knowledge. One thing I have learned through studying investing is to try and not underestimate how the general populace will react to something. Those potential buyers are going to read or hear about fake coins and most will avoid that type of coin. Can the Pandas still obtain a sizable premium even in that circumstance, yes, but IMHO the odds are not in favor of them doing so, especially with a massive increase in the mintage of the new years. So, my pm purchases will be into other coins that I believe have a better risk/reward ratio for premium increase.
One important question. What are going to do when a dealer sends you a fake Panda or Pandas and won't take it back? When Tulving sent me 3 1988 AGEs with deep scratches on them out of a 220 coin order ( most not mine

), I called him about returning those coins. He said I don't sell coins like that and hung up on me. Similar results from Gainesville and Providentmetals for damage from bad/sloppy packaging. Unless the coin is slabbed, how do you prove where you bought it? I don't believe that you can prove where you bought the coin and one fake coin will wipe out a lot of premium on the others. So, being able to tell that the coin is fake still leaves you dependent upon your relationship with the dealer. From buying over 1 million dollars in coins over the last 3-4 for myself and others (mostly others), I have learned that the US dealers do not make good on replacing defective coins or coins damaged through faulty shipping. So, I have -0- confidence that the US dealers would take back any fake coins. From reading this board over the last year+, I believe the AU dealers are more ethical regarding problems. But my position is to avoid the risk.
Hopefully, the Panda investments work out well for those who buy them. Opinions were asked for and I gave mine. Time will tell which opinion is correct.
