I found a Colt belt buckle at my local thrift shop and am trying to find out what the value of it is. It is marked Wyoming Studio Art Works on the back with a G-10 imprinted at the bottom. The only ones similar that I can find online look like this one but have "souvenir" written in the upper left hand corner. The one I have doesn't have that. Its very heavy but I don't know the material its made out of.
