Here's a pic of the maroon hot stamp chip I found when Paul Bender and I went out on Sunday. All total we got about 30 tokens, a lot of concrete pieces, some with impressions only, some with tokens, and some with chips. Also ended up with several good $5, $1, and $25 chips. Separated a bunch for the club museum.
Here is the scan of the hot stamp chip. Not in the best shape but for a piece of clay in concrete for 20 years, it's not bad.
Saw the rebar with the bottle that Barry marked for the spot, but we found all of our stuff in a different area.
