I picked up a box with some assorted vintage Las Vegas items at a local collectibles show this weekend. In the mix of items were several chips including these 2 chips. I don't know what they are, can someone please help me? One chip has horseshoe mold, BC on one side and 50 cents on the other, the other chip has AJS on both sides. I might be interested in trading for some other Vegas chips if anyone is interested. Thank you. David
