Found this in a register at work yesterday. At first I thought it was a cent from the obverse and when I turned it over the toning and fingerprint made for a neat find at the cost of a dime.
Here is my set of 1940 P, D, and S Mercury Dimes. I am very proud of this set. The P I purchased in MS65FB (OGH) for $35 and PCGS just upgraded it to MS67FB. The D I purchased for $190 in MS67FB and PCGS just upgraded it to MS68FB, making it crazy valuable. I just purchased the S in MS67FB to complete the set. I have never been so lucky with PCGS submissions; these two coins were great pickups . . . .
