1849-O Is for sure a hard one to find that not a cull.and I live in the south were most of the O mint are found.
I'm sort of a Dime collector. They are for some reason one of my favorite coins. Presently have 8 completed sets of Roosevelt Dimes, 12 completed sets of Mercury Dimes, 3 not so completed sets of Liberty Head Dimes and only one not so completed set of Seated Liberty Dimes, a few odd ball Bust Dimes and a few odd ball half Dimes. Largest amount of them is my many rolls of Mercury Dimes which totals about over 3,000 of them. Aside from the 1943 Lincoln Cent, Dimes are my favorite coin.
