when you provide better information. If you are not sure of the number, the condition, or even the casino, it's hard for anyone to give you reliable data.

I suggest you photograph them, count them, and come back with that info. If you are unable to do so, send someone who can. Otherwise, you will get advice like "they're worth what someone will pay for them," which is not useful at all. You will feel let down, but you haven't defined what "them" is yet.

That's just the nature of this hobby. There are too many variables, and the future is hard enough to predict without having to do so in a vacuum.
