This "Seniors" tournament made the rounds to several card rooms as I recall.
Here's a similar chip from a Seniors tournament held at Oceanside Card Casino in Oceanside, CA.
It's one of a whole series of such chips -- See pics on the Chip Guide, where this image came from --

When Oceanside was still open, they had some racks of these in their cage.
Don't know what happened to them after closing.
