I am a routine reader of The E-Sylum and thoroughly enjoy it! I'm not quite a coin collector anymore - I moved some years ago to silver ingots, cast, poured and extruded. I began with a 5 oz hallmark collection and then moved into government mint and assay ingots which have become my passion. While my focus is on 5 oz class government ingots, I have digressed into some larger examples over the years and am finishing a paper addressing the authentication of Type II San Francisco ingots.
