What have you got, PASCOAL ¿ ?

Though I can not locate my actual notes (from about 1992) attributing this chip to a "Club [Casino] Atlantico" in Portugal, I do recall the period of operation being late-1920s... and a private club catering to the English (Does this sound right, Pascoal?).

The piece is engraved; 33mm, thin, and seems to be a Celluloid-type plastic. I've not performed any tests to help determine composition.

A balance of an equally rare Mother-of-Pearl gaming plaque or chip will work well for me.
