The 1938-S Mercury dime is a common coin by all accounts, with plentiful specimens in all circulated grades and thousands of uncirculated Full Bands specimens. This piece is readily available through MS66 and much scarcer in higher grades through MS68. The 1938-S Mercury dime set an incredible price record for this series when a rainbow-mottled example graded PCGS/CAC MS68 took a whopping $364,250 in June 2019.
