I did a quick scan of my inventory list for Civil War tokens to count just the R8 (5-10 known), R9 (2-4 known) and R10 (unique) tokens, and I counted 78 but I could have easily missed a few. I also have about a dozen and a half unlisted cwts, and a couple hundred cwts waiting to be logged into my system that undoubtedly will have some in the single digit pop. range. The avatar of my ancestor's token is an R8.
I recently picked a hard times token, Howell Garden Works Low HT-201. Not the most valuable coin but pretty interesting. I like the history associated with time period and the big rose on the front is pretty cool.
My favorite is a 1900 V-nickel Proof 67. It is a wonderful coin and I will hand it down to my children someday, and I hope they hand it on to theirs.
