Fr. 1610. 1935A $1 Silver Certificate "S" Experimental. PCGS Currency Gem New 66 PPQ.An incredibly popular catalog number with this "S" overprinted note being produced on "special" paper. The note was released alongside its "R" counterpart for a trial in seeing if the new medium would withstand the rigors of circulation better. This bright Gem example fortunately for collectors was not able to provide data to the B.E.P. as it is still as nice as the day it left the money factory.From the Marc D. Cohen Collection.
