<p>[QUOTE="rmpsrpms, post: 2858804, member: 31773"]Hmm, I agree with a lot of what you said. I think we're getting somewhere! I don't see much point in arguing about proofs vs business strikes, but I do think it will be instructive to look at VEDS vs EDS vs MDS vs LDS. I might have a progression available to show that, I'll need to dig something up and snap some shots. Note that even in EDS the flow lines start to produce luster, so you really must go back to VEDS to see the flat nature of the resulting coin. Another possibility is a die that received a bad clash and had the surface ground and polished such that the flow lines were removed, resetting the process. </p><p><br /></p><p>Just for fun, here's a pic I took of a 1994 IIBIE showing the flow lines worn into the die.
