Actually, it's a long lost Morgan reverse pattern found rolled up in the binding of George's sketchbook in the Smithsonian
I've heard of it, but that's all I know of it. $10.00 is a great price, someone lost out on the grading fee.
I have a question, so when we see serious die-polish lines, that means there was a die clash that needed to be removed from the dies, or are there other reasons this might be necessary ?
Many potential reasons. Start with the knowledge that during WW2 (starting in 1941), Dimes were minted in quantities which dwarfed any previous US silver issue. In fact, in 1942 Philadelphia set production records for every single denomination to that point. They were busy, creating record numbers of dies, and individual dies could not have gotten the normal amount of attention. This could well be the initial preparation polishing, and the very earliest coins struck by those dies could have looked just like that. It could have been an attempt to remove the artifacts of die wear, surface striations and the like. In the case of Cascade's 1942, though, I'm thinking it actually_was done to remove clashing artifacts. The polishing on both faces is at its' strongest in the areas where Mercury clashes appear the strongest.
Thought I would post this here as well since it was a purchase under $50.00. Picked this Lot #3 up at a friends local coin club auction for $2.00. Most all the lots sold for under estimate price. I bought the lot obviously for the clip but the 1919 had a nice rim-to-rim bisecting lamination crack as well.
Free shipping, I put an offer of $12, which was quickly accepted!! Big fan of the springbok, and every coin she adorns!!!
