My father gave me a $10 solid sterling silver gaming token from the El Dorado Club in Gardena, California (now the site of the Hustler Casino). It is in mint condition.

Does anyone have any thoughts on the token's value? Or, does someone have suggestions on who I could contact to determine the value of the token or have a recommendation regarding a book or website which might be of help to me in determining the value?

Thanks for any help.
