Back in '91 I made a pair of knives and used the crown sections of a big whitetail rack. on the polished crowns I inlayed two uncirculated 99.99% silver undated Morgan dollars, one on each knife handle crown. I placed one heads up, and the other, tails up. The 1 oz. coins actually turned out pretty good on the deer crowns. The coins then just cost a few bucks each. Silver was about $4 per ounce, the coins just a bit higher.I have done quite a bit of inlay using pure silver 1 oz. ingots. I imagine the ingots would be pretty good for making mokume, huh?
