I have three tokens that I got at McCarran Airport. I am looking to find out how much they are worth.
The outer rim is gold an it says: LIMITED EDITION TEN DOLLAR FAMING TOKEN. McCARRAN AIRPORT In the middle is the Liberty Bell in silver. The other side has two planes.

I have two other tokens the same as above except one side is the Twin Towers, and the other is the the head of the Statue of Liberty. Can anybody tell me what they are worth. All three in plastic case, never opened, and in mint condition.
