Ran over to ChipGuide real fast knowing I saw the same embossed graphic somewhere and then saw the £1.00 plastic chip. Then I thought it might be listed under Casino Club London by mistake. Couldn't find it and ran back to eBay to snap it up. I'll make it up to the seller with a balance of stuff he can sell and do well with. Thanks.

About the gold. There's nobody left in Chicago who would remember, so it's a matter of finding a family member of the jewler who cast it. Impossible, right...!!!
