I found this 1957 D LWC and it is a different monster to say the least. It weighs 3.04g and looks like it might have been encapsulated at least until I looked at the collar. The whole collar looks like the start of a planchet ready to split and this cent is smaller in diameter than a regular cent. Why would it be smaller in diameter than a regular cent even with the rim pushed outward on the obverse AND reverse? Could this cent have been punched using the a foreign planchet? Insight needed on this one!

Looks like a former Encased Cent.

That's kinda what I'm thinking too John1. What I'm trying to finger out is how did the diameter of it shrink with the rim folded outward?
Rest in Peace

The encasing process is a high pressure hydraulic press. When downward(and reverse upward) pressure applied, this "bends" the rim down and outwards. This is the way the softer aluminum is forced into that recess, to help hold the coin in place. No, just a standard planchet...tolerances are 3.1g +/-.13g, well within that limit.

And another point, this baloney about foreign planchets, just that. The manufacture of stock plating/extrusion(thickness), can vary in microns all along the same plate even. A blank cut of thinner/thicker points on the plate will have even grater variances than the official "tolerances". These tolerances/are NOT an exact science, too many variables. Is this a mint error, or just a random machining flaw? Apparently some are pushing this as a mint error, I beg to differ.
