1981-S 10c Roosevelt 10c, as shown. This is in a scarcer PCGS holder that shouldn't exist, according to them (see 3rd picture). Regular issue coins should have had a Series and Coin number. Corresponds with the Condor101 Gen. 6 holder as used on the forums (before PCGS published their Museum of Holders).
Will be offering several of these this and next week.
$100 reward for a 1938-D Buffalo Nickel MS66 in this style of holder!
