I don't know of an online site for token info. You should have Janice O'Neals great list of Nevada tokens, though. Most every dollar token (and many 2, 5, and 25) is listed and given a catalog number. Vince Mowery had a price list of tokens that he sold several years ago. Out of print now, but he says he's trying to update it. There are books put out by Krause Publications on Franklin Mint items, including tokens. I believe these are also out of print but available sometimes in used book stores.
