Is the data in the NGC / PCGS price guides supposed to reflect current market value? If not then what are those numbers suppose to reflect. I have been watching various eBay auctions for NGC PF69 coins and they seem to be closing at about 66% of the NGC Price Guide levels. The PCGS Price guide also seems to indicate lower prices then the NGC Price guide, but also above the eBay prices. Since PM prices have been increasing rapidly, and the data in the Price Guides are a trailing indicator(reflecting historical information). I would have expected the values in the Guides to be below the current market prices. Isn't eBay a good indication of market value since so many dealers participate? Thanks for your assistance and insights.
