[QUOTE="Elendis, post: 4629231, member: 113665"]Update: After further analysis, I've found that the entire coin is missing a proto-rim. [ATTACH]1145355[/ATTACH] In fig. 1 you can see the rim developed from the die press. [ATTACH]1145356[/ATTACH] In fig. 2 the absence of a proto-rim is apparent. This rim pattern continues around both faces of the entire coin. The two possibilities that I've thought of to explain this are that either the proto-rim was sanded down to imitate possibility 2 (most likely), or the penny was struck on a blank planchet, but that would not explain the edge being smooth. My best guess (in favor of myself) as to what could have caused this is that the penny was struck on a type 2 blank: from [URL]https://www.ngccoin.com/news/article/328/[/URL] The edge of the penny is relatively smooth, but has irregularities and scratches that make the coin having been sanded from a normal state seem unlikely.[/QUOTE]
