[QUOTE="RonSanderson, post: 3336647, member: 77413"]I’m going to have to learn more about die misalignment before I can answer your question. I do have one very obvious thing left to mention. When you examine the closeups of the two dimes the surfaces are quite different. The satiny 1941-S exhibits only very fine-grained radial flow lines. There are no lines that look like die polishing that I can find. The reflective 1939 (surface details in post [URL='https://www.cointalk.com/threads/lets-see-your-newest-acquisitions.158772/page-1181#post-3331363']#23601[/URL]) has die scratches that run in many directions. Because they are scratched into the die they end up raised above the surface level. I expect the cross-section shape of the lines to be quite different, too, since one is created by erosion and the other by scratching. There are two quite different surfaces and very distinct lusters. I also have a question. When a new die starts out Proof-like, the mirror smooth die immediately starts to erode. I would think an early stage of wear would be just light radial flow lines. After a touch-up there would be polish lines in many directions. Do all new dies go through a brief stage where they produce satiny finishes?[/QUOTE]
