Someone has a playable set of these:

These are from the Chesterfield Club in Detroit, an underground casino run by mobsters in the 1920s. The "CC" chips were also later used by the same mobsters in the Nevada Club in Reno in the 1940s.
A playable set of these was listed on eBay in 2016. No telling who owns that set now, but it exists. See https://www.pokerchipforum.com/threads/chesterfield-club-800pc-set.12192/
I sold a set of 6,000 chesterfield chips to a buyer fifteen years ago. So there are a few playable sets out there.
