I have a $500 Nevada Club chip that says "not redeemable" on it. Does any one know what the value is? Also I have a pair of cuff links that say Sahara Hotel on them and they are in the shape of a craps table with 4 people standing at each side. They are gold and black in color, made by Winsor of Beverly Hills. Would like to know the value of these also. Can send pictures if necessary. Thanks in advance.
