These prices are not intended, and should not be relied upon, to replace the due diligence and - when appropriate - expert consultation that coin buyers and sellers should undertake when entering into a coin transaction. For all of these reasons, the prices in these guides are designed to serve merely as one of many measures and factors that coin buyers and sellers can use in determining coin values. This is especially true for rare coins, where there are fewer sales and greater variations in sale prices. Further, because these prices are only updated from time to time, they do not reflect short term pricing trends, which are quite common and are often quite dramatic, given the volatile nature of the collectible coin marketplace. Prices provided are averages, not specific prices for individual coins. Disclaimer: The prices listed in the various NGC Price and Value Guides are compiled from a number of independent, third party sources in the numismatic community which NGC believes to be reliable.
