I have 3 chips that I am trying to find an approximate value for. They are all circa 1951 from Binion's Horseshoe, LV. One is a $0.25 chip with a pic of the casino on it with red and green stripes, uncirculated. The second is a $25 chip which is green and white, uncirculated. The last is a $5 chip with a pic of Benny Binion, signed, and it's olive green. Any information on the above chips would be greatly appreciated. Thanks!
