[QUOTE="ToughCOINS, post: 8422068, member: 20480"]I enjoy challenges such as this so, time permitting, it's hard to let go without reaching a well-supported conclusion. I know some members promote this as undeniable fact. I do not. Planchets are designed and made smaller in diameter than the finished product for the very reason this is not true. Reeding is formed by the outward expansion of the planchet into the collar when struck. It is not until the outward flowing material is substantially confined that it flows inward. Consider the accentuated outward erosion of dies from stars to rim on Capped Bust Halves despite the proliferation of weak central strikes of that design. As described in the last paragraph, you should not expect the date to be disturbed before details closer to the rim. The upset rim is work-hardened before strike. Striking through most any soft debris, such as grease, wood, fabric, tape, etc, would clearly leave the upset rim largely intact. Striking through something so hard as to obliterate the hardened rim is plausible, but I'd expect to see abrupt interruptions in the rim at both edges of the debris. That is not evident in your photos. I continue to posit that the planchet delaminated in this area before strike.[/QUOTE]
