What To Do With Duplicate Mercury Dimes

Just to add one more thing to my Mercury dime mania, yesterday I purchsed 45 more Mercury dimes from my favorite dealer at the flea market for $40. With those and others recently purchased, I am still trying to put together sets #11 and #12. For weeks now I have been going through all duplicates, opening up 2x2's, sorting through rolls of the stupid things for the best grades for those sets. I was a little shocked that out of all the duplicates I was missing several. Naturally no 16D, 42D/41 duplicates. However missing 2 of the 1925D's and 2 of the 1930S's and 1, 1931S. So with a coin show tomorrow I should be able to find those there. So set #11 and 12 will only be short 2 coins after that. Now if I get another Album from my friendly dealer free, it might mean another set but just don't want anything to do with 13, not that I'm superstitious.
