I collect casino tokens as well as coins. I've seen lots of quarters and halves that were painted red in an attempt to make them less attractive to tourists but don't think I've seen a sand-blasted Harrahs dollar.

Here are some Harrahs coin key-fobs I've found.

In my opinion, the disappearance of silver coinage from casinos was due to the debasement of the country's currency, not to collector interest. As you know, at one time silver sold for over twice what it does today. I even saved 40% silver halves in the 1960's when they could be picked out of bank bags. They are worth 5-10 times face value today just due to the value of the silver contained.

I miss the ring of silver on tables and from the machines but what killed that was again due to debasement of the currency. Paper vouchers that could be accepted and disbursed by machines were much more convenient for players to use. And the loss of value of dollar coins and tokens for table games was mostly responsible for the removal from play of the metal playing pieces. Table minimums of a dollar or two are seldom seen any more, with $15-25 minimums much more common.

For token collectors, the $2 tokens that were produced in the sixties and seventies are a scarce and seldom seen variety. Actually, some clubs even offered $2 play in their High-limit rooms and this lasted until paper vouchers replaced them just a few years ago. There are only about a hundred different Nevada $2 tokens that were intended to be played in a slot machine and this can make a very enticing area to collect. Since you mention Harrahs, here are a few $2 slot tokens from different Harrahs locations that are very collectible.
