Those were from one of the TRK standard home game sets. IIRC they had three home sets, generic numbers like above, Kings Crown, and a weird fake bone looking set.
Just got back from the wayback machine and I can see the other sets (the bone was "ivory") but I don't see that one, though I know it existed with denoms 1-10,000 IIRC.
