I have 95 slot cards. Most I have had around for years. I would not krow a "good" slot card if it jumped up and bit me on the arse. There is some very light duplication on a very few. They are not all Nevada, though most are. I have no idea what a fair price is. Make an offer. I know there is a couple of different West Virginia cards which I know have to be scarce. You must wear shoes to get into a West Virginia casino. I know because I lived there for 40 years. You know how Hillbillies are. LOL My scanner moved while scanning thus the reason for the top row.
