Sheldon 250 is one of the 1803 Small Date, Small Fraction varieties. Both Breen and Noyes call it Rarity 3, which makes it somewhat scarce as a die variety. There are probably ten examples that would qualify as Mint State upon examination by PCGS; indeed, five examples have earned that distinction as of this writing (9/2015). The best example certified by PCGS is an MS65BN. Dr. Sheldon graded one MS70(!) in Penny Whimsy, but that example has not been seen in decades - who know what it would grade today?
