I have some UK obsolete plaques and chips, as well as a Stardust $1000 oversize commemorative token issued for the CC & GTCC convention a few years back - from memory you had to take a token issued at the start of the convention to the Stardust cashier and they issued one of the tokens to you.

Nice items, and on Ebay now

Thanks for looking

Jason
