I received my package—all bought after the first hour was up. Awesome overall. The minty 25s and 500s will go into my mixed Jack sets right away.
Note on the used THC $1s which may be of use to others:
I bought three racks. These separate very clearly into two grades: Nearly mint and Used.
The ratio in my batch was pretty much exactly 1:2 (1 Nearly Mint for every 2 Used).
The two grades were mixed together in the boxes, but when viewed on edge the mintier ones stuck out really obviously. The newer ones are much whiter. The more used ones have a slight pink-grey cast, especially obvious on the rolling edge.
Within the Used 2/3rds, there are a small number which are much more used. I’d say maybe 15-20 out of the ~200 Used grade chips.
I’m going to give the Used ones a Faux TSP bath; I expect this to upgrade another rack of them to looking nearly new.
In short: If (say) you wanted two racks of Nearly Mint Jack Cincy $1s, without having to clean any or accept some slight rounding, you probably need to buy six racks to cherry pick. If you are willing to accept some signs of use, and to do some cleaning, that number I anticipate will be more like 300 to get 200. Will revisit after cleaning.
