I'd have to say my top buy was my cherrypick of the 1874
Seated dime I bought in December, the one I mentioned here last month which has only one arrow in the date prominent.
I've been discussing the coin with series specialist Gerry Fortin and he seems to think I have a "discovery coin" for a new variety, one which uses the same obverse as the F-106 variety which has only three pieces known but with a different reverse than F-106.
