I have a question about the "21 West Elizabeth," Detroit, Michigan, crest and seal chips. See pictures below -- both sides of the chips shown, which happen to be mine.
Questions:
(1) the ones with "1" and "10" on one side are roulette chips from tables #1 and #10?

(2) if so, isn't it inconvenient to have the table number on just ONE side? Harder to spot a chip on wrong table if table number is just on one side. Unusual design for a roulette chip?

(3) if so, there should be similar chips for other table #'s? But no other table #s known for the place?

(4) one chip has "50" on one side. Why? What used for?

(5) one chip has "10¢" on one side. Why? What used for?

Thanks,
Robert
