So I work in table games in a casino. The chips that we have are top hat and cane. The denominations are $1, $5, $25, $100, $500, $1000, $5000, and $25000. Even in the poker room they use these denominations (though the 1k and up aren’t readily used). So I see a lot of nice sets on here. But in place of the $25, they have $20. The casino in me cringes. What is the reason for a $20 chip instead of a $25?
