Description & Analysis

In 1964, the United States faced a coinage shortage. Due to this, the mint ceased production of normal proof coins, which required significantly more work with die and planchet preparation. As a substitute, they created the Special Mint Set, which contained coins that weren't quite proofs, but were clearly of a higher quality than normal circulation coins. This allowed the mint to place more resources into producing coins for circulation. These special sets were issued in 1965, 1966 and 1967 before normal proof production started once more in 1968.

NGC Price and Value Guides Disclaimer

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. Prices provided are averages, not specific prices for individual coins. 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. This is especially true for rare coins, where there are fewer sales and greater variations in sale prices. 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. 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. As such, NGC disclaims all warranties, express or implied, with respect to the information contained in the NGC Guides. By using the NGC Guides, the user agrees that neither NGC nor any of its affiliates, shareholders, officers, employees or agents shall have any liability for any loss or damage of any kind, including without limitation any loss arising from reliance on the information contained in the Guides.
