I've scanned the chips. I was mistaken when I previously stated that the chips were large crown and hub. Thats what I get for not looking at the chips before I posted. I also discovered an additional font on one of them. So there are three different chips:

Large Crown, "JD"
DIASQR: Small "JD"
DIASQR: Large "JD"

For those of you that missed my original post on these chips, I found them all together in San Diego. I only have three of the large font "JD" and one of them is worn on one side. The other two molds I have around of 10 of each in various conditions. Some with cigarette burns and others in great shape.

If anyone knows the id on these, please let me know. I haven't found them in my references.
