Good morning. My book has the $25.00 listed in it because it is made of .999 silver. Should weigh in at 1 ounce. Not common but not what I would say as rare to find. Most of the $25.00 .999 silver casino tokens from all casinos have been added to collections or sent off to melt.

I looking at Dan Wicketts site and book the $1.00 is the Grand Opening token that originally was on a card and sold in the gift shop. Proof but not .999 silver. Dan's guide says value as $15.00

And on the $100.00 it is one of three $100.00 tokens the HR had. This one is from 2001 made by Osborn Coin (OC) mint mark. Made of nickel silver with brass center piece. Dan's book values it at $150.00 .

Hope this helps.

Dennis
