Funny story about the Grey $2.50 the lady that just sold it worked at harrahs in the Main cage. She said a lady returned that chip about 12 years ago to harrah's for face value. Harrah's put it in the obsolete and to be destroyed rack. And she talked her supervisor into letting the but it. Talk about a return. Anyway Don't know if it is true but a great story anyway. Take care all.
