If you punch the same to as your post to Google. It will pull up pcgs price guide. Also shows auction listings, for same coin. One grade up and one down.
? Was trying to help. I definitely use it for any Pcgs, Ngc and Anacs slab Anacs ( undergraded) soap box slab.
PCGS values this coin at $65.00 without the DDO designation. There are 2094 PCGS graded MS66FB. There must be a lot of these coins exhibiting this doubled die variety. CPG removed this variety from the chapter on Mercury dime varieties in Edition 6. CPG cites "Low Interest Factor". The coin is cataloged as FS-10-1937-101.
Should I at least try and resubmit to get the proper designation on the slab just for my own piece of mind?
PCGS specifically excludes 1937 FS-101 from their designations as "too minor." They won't attribute it. http://www.pcgs.com/cherrypickerexclusions You ask intelligent questions, but would likely be surprised at just how many answers are already available on the Internet.
There is no "tarnish" There is a small amount of toning. Also, I don't see any scratches, some die polish marks, perhaps, but no scratches.
