While Series 1935D $1 Silver Certificates were being issued, the back design was made about 3 mm narrower. All 1935D notes are either the wide or narrow variety. This Series 1935D $1 Silver Certificate bears Clark-Snyder signatures and features the "wide design" style. Once redeemable for silver coin or bullion, small-size Silver Certificates, with their distinctive blue Treasury seals and serial numbers, are among the most sought-after U.S. currency notes.
