Went through over 500 steel cents just now and found a cent that is 2.51g it feels light, weirdly light almost like holding a alum coin. sticks to a magnet too. Same size as normal steels. Also found a 2.96g steel cent.   |

Thin and thick planchets maybe? the coins have the same diameter all around.

What does it look like from the side when you stack the 2 of them with a "normal" 43?

A US 1943 dime planchet weighs around 2.5 grams, but yours is magnetic so that rules that out.

the thin 1943 and the thick 1943 I have can be told apart easily when stacked with other 1943s.

Specs call for a thickness of 1.55 mm and a Weight Tolerance of + or - 0.13 g. Seems like yours may be a little out of tolerance, but I do not know how much that must be to be called thick or thin. I suspect that definition is not precisely defined. I searched for a definition so precise but did not find it...perhaps someone knows. (?)  |

There does seem to be a little weakness of the strike. (reverse devices) But the rims are pretty well formed.

With a missing clad layer on a dollar the weakness can be seen on both sides.   Note the overall weakness just from one cladding missing? If the planchets are thinner, then the strike will be weaker. Not a Struck Through Grease because the rims are almost non existent. So seeing this coin with two normal coin on top and bottom of this coin might be a better way to see why it is under weight. The zinc looks intact, so it was plated that way. Not altered before the strike. Edited by coop

Steel cents were struck to two different weight standards. 2.5 and 2.7 grams (roughly) A 2.96 gram coin would be out of spec but not a 2.51 gram coin.

i did weight on all 500 steel cents they were pretty much all within the error value of the weight or the weight except the 2.51g and 2.96g I put everything on my scales when I look for errors.
