I beg to differ Gentlemen. Casino Windsor ONLY issued the silver strike in the $20 denomination.
As you will note in the previous auction listed for $24.99 only the theme side is shown. The logo side contains the denomination and believe me they are $20. Flip it over Vegasplayer. If so let us see the scans of the reverse side showing the Casino Windsor logo with the $10 redemption value on the rim.

If you are very nice to me I will explain why this is a ten dollar style strike with a $20 redemption value.
