The Bonanza used to be called the Bonanza Inn, and these chips were in use several years ago. Then, as I understand it, they went into the vault, the casino dropped the "Inn" from its name and began using $1 tokens on its only craps table, which still uses 25-cent chips.

This chip resurfaced about four years ago.

A side note on the Bonanza: A friend of mine was in there once and won $70 playing craps at that same quarter-minimum table. They practically escorted him out of the place. I got the feeling they thought they were headed for bankruptcy after this "major score."
