1949 Possible Clipped Planchet

I don't think so. The rim and denticles above the E in STATES look like they were displaced after it was struck. Very neat coin though- it looks like a nice straight clip.

The edge at the bumps is shaped like a 12-sided Canadian nickel-perfectly machined joined. I'll try and have some pics. You can see which direction that it went through the upsetting mill, just like the OP's '49 Linc.

My point is that if the upset mill did change the shape of the edge and force the proto-rim deeper into the planchet, that part would be obliterated during the strike. It just couldn't change the shape of the denticles in that way.



How was the edge lettering applied? Just milled before strike and allowed to expand a bit?

Ummmm, Steam-Powered coin presses were introduced in 1836; collars were used earlier, but they were "Open" until 1827/8 (the JR-1 Small Date 1828 Capped Bust Dimes are good examples of the closed-collar strike)

"...The five authors of Early United States Dimes: 1796-1837 believe that the classification of Capped Bust dimes as Large Diameter and Small Diameter varieties is incorrect. Instead, they believe the changes in diameter resulted from changes in minting equipment, specifically the collar, in the late 1820s.
Prior to 1828, edge designs were applied to silver planchets in a separate process before striking (generally). Planchets were placed into a Castaing machine, which applied the reeding, lettered inscription or other edge design appropriate for the denomination and date.
In order to not damage the edge design elements during striking, an open collar was used. The opening in the collar was larger than the planchet. During striking, the metal of the planchet spread slightly, but not to the limits of the open collar (as long as the planchet was centered properly on the anvil die).
The introduction of the close collar, however, changed minting procedures. The open collar was replaced with a close, reeded or grooved collar with a smaller opening. The planchet spread during striking, with the metal of the edge flowing into the grooves inside the collar. The use of the close collar eliminated the need for the open collar and Castaing machine, since the designs for all three sides of the coin - obverse, reverse and edge - were generated at the moment of striking... although slight modifications were made when the close collar was introduced to replace the open collar about 1827-28."

I am skeptical that large cent is a genuine clipped planchet, and I am certain those rim bumps are not from the upsetting mill

When we put high closer view, we can see clear that the cracked planchet was detached before milling. The structure of the metal say everything. If was after milling the crack borders will not be round. This it is the physics and material proprieties and we have to accept.

@silviosi: I'm a "striking junkie" of sorts... back-in-the-day Walter Breen and a bunch of us from EAC, etc would have dinners at the major conventions, and share all the things we cherried. THose days, it was pretty easy to cherrypick 'broadstruck' Draped Bust Half Cents (actually, they hadn't traveled through the upsetting mill)...

And yes, even if one applies the most rudimentary forms of Physical Laws to coin striking, then one should be easily able to figure-out if the coin was struck by error, or falls victim to PMD
