Ed, I have a $12 one of these sitting around, so if you find a good place to sell yours, let me know.
Now, that is interesting. I've never seen a $12 gaming token before. All of the ones that I have or have seen are $10 tokens. Do you know if there are any other denominations? Just curious.
I haven't sold my tokens yet but am looking for a place that will buy them. I haven't tried my local coin shop. Don't know if he would have any interest in these at all. If he does, I suspect that it will just be for the silver content.
There actually is a club of people who collect these things. If any of them needed specific tokens to fill out their collections, they might be willing to offer a decent price - more than just for the silver content, anyway. Check out Dan's Casino Tokens web site. I can't post the URL yet but a Google search will find it quickly.
