I recently purchased the entire inventory (except for a few kept by the casino) of $500 slot tokens from L'auberge Casino Resort, formerly L'auberge du Lac, a Louisiana casino. I had acquired a few of them and sold a couple, but I now own nearly all of them. Most of the tokens show minor wear and tear from use, they were in use for about eight years and removed from circulation in 2013. Token is 39mm, slightly thinner than a poker chip, and will fit in a standard chip protective case. They are two tone with a gold ring and a silver insert, tokens are made of a light, durable metal as they were manufactured for use in $500 slot machines. I've included a couple of pictures, there are additional pictures in the eBay listing.
I have them listed at $24.99 but I'm willing to take offers on purchases of multiple tokens. I'll also make a deal if you'd like to purchase directly from me rather than eBay, as it will save on fees.
Please email with any questions or for more info.
