on the purpose of the $5s-- I had always wondered why they had a denomination so small, and why they included the $50 in the progression; as you mention the commission on the $20 would be easy to calculate, and similarly the $100. However a $2.50 commission on a $50 bet just didn't seem like a 'round' number, which puzzled me why they would use it. However, it makes total sense that, like the $5, it would have been used to pay commissions on even larger bets.

When you state "It is believed that only a hundred or so of the $5 jetons exist.", did you mean 'ever existed' or 'were made', rather than the number (presumably far fewer than 100) which survived and exist today?

In any case, thanks for sharing! One of the better looking chip designs out there from an iconic casino.
