I have a report on the results of going thru the first of two boxes of halves. (see original post: boxes & boxes)
The first thing that struck me was the sheer number of them that suffered from one armed bandit syndrome. 10% had no edge reeding left whatsoever. Fully 40% more showed at least some evidence from slight to moderate. Unfortunately, any time spent in that environment trashes the rest of the coin almost immediately. Biggest disappointment was that in that batch of slot coins was a Coneca & Wexler 1974-D DDO#1 so damaged that it's only good as a type coin.
I did find (10) 40% silvers and enough AU & BU specimens of the clads to fill most of the holes in my Dansco album. All in all not too bad. Going thru halves is not too time consuming as there isn't that much to look for. There is something fun about peeling back the wrapper and seeing a grayish silver edge nestled amongst the clads. Sorta like an Easter egg hunt. I'm sure that the abundance of slot coins can be attributed to the fact that the casinos are only an hour west of here.
I tabulated them by distribution instead of chronologically as I feel that is more interpretive. Mint mark frequency is also skewed I'm sure by the fact that I'm in Denver.
