My brother (Oakland, CA) found some very damaged (water deterioration) chips as follows: (Sorry, no scanner here in Vegas, but believe me, these are highly damaged! )

Hub-Mold, light orange, $5.00 on one side, "Aqua Caliente Jockey Club" in script on the other side. Hot-stamped.

Small Key-Mold, light orange, "327 Club" hot-stamped on both sides.

Rectangle/Heart-Mold, light orange, "JD" hot-stamped both sides.

Any insights?

Thanks,

Jim
