Validating just another annoying typo in the 2006 Red Book, which shows the value of a 1938-D Proof as $125 and a 1938-S Proof as $7 <scratches head>. According to PCGS Coin Facts there is no such animal. Just wondering if the mint made some wacky wild special set for FDR or something. Otherwise I will just write this off as another error in two lines of text that shouldn't have changed in 68 years. Per PCGS Coin Facts: Date Mintage for Mintage Circulation Proofs 1938 19,496,000 19,365 1938-D 5,376,000 0 1938-S 4,105,000 0
