much more than I do and have been around collecting information much longer than me.

Do you have any idea where this piece of glass was used, which casino ? I can tell just by looking it was from a machine that the $25 face valued .999 silver tokens were used but sadly no casino name on the glass.

My thought would be Circus Circus but they did not have $25 silver tokens, so that's out. I put the three different silver tokens in the glass for fun, not stuck there.
