Original sealed 1964 United States Mint Proof Set Tennessee Valley Hoard. Once in a lifetime collection We are proud to bring to auction the greatest proof collection of the late 1950s and early 1960s. This collection may contain some of the only unopened mega boxes of unopened proof sets still in existence. In all my years in numismatics I have never seen a collection like this one. Finding cameo and deep cameo proofs from this era is near impossible u less you pay full retail and buy them already holdered. All of the sets at coin shows have been examined and have virtually no cameos. The only way to get the same odds of finding one of these valuable cameos is to buy an unopened set. Many sets today that are purported to be unopened have a actually been opened and resealed or put into a fresh envelope and sealed. This 100% original lot is guaranteed to be unopened from the day it left the mint. We will cover your laboratory costs and pay you 10x your cost of the set if the carbon dating on this set shows that the glue is not from the late 1950s 1960s. A true once in a lifetime opportunity
