Hard to find SQINCR $5 red poker chip from the Joker's Social Club (closed) in Vancouver, BC, Canada
Made by the Portland Card Company (also closed) using the Square In Circle mold (SQINCR).

I'm not sure of the material. Sounds like clay.

You don't see these too often.

The chip has been played but is in great condition, a bit of grime on the edge, no damage. It has not been cleaned. Bold and bright logo. I would rate it Slightly Used.

It's unclear wether the Joker's Social Club was a legal establishment or not.
