The yellow $5 B-G is from the 19th Hole, and the cardroom still exists, although they now use 19th Hole chips with a few BG variants in the cage and not for sale.

BG $1 blue (note: no dash or little diamond between the letters) would be Betty Gates Card Room in Ridgecrest, CA. No longer open.

The most confusingest pair o' chips in California and the question arises fairly often around these parts.
