Lincoln Cent With Odd Weight

It's difficult to say without pics. The appearance and condition may give clues as to what is going on, so...

As promised below are the images of the 1982 cent

I understand 1982 was the transition from copper 3.11g to zinc Lincoln cents weighing around 2.56g.
And since the U.S. Mint has a Weight Tolerance maybe 2.90 g is within it.Honestly, I have a 1982 and it looked like all the other 1982's, 1983', 1989-D's I was weighing except some were RB or RD.
When I weighed it;it weighed 2.81g. I weighed and reweighed it, lord knows how many times.
Then got a Wheat penny and put iton the scale and it weighed 3.11g so then all those Zinc, 2.56g ,a few made it to 2.64g just to convince myself.
If they already went to copper when this was minted; it would have to be considereda transitional error but it's not clear cut as the guy with the 2.90 g 1982-d.
Because if it's a small date 1982-D weighing in at a weight that is torerant for co]er pennies, he just hit the jackpot.
I hope its a 1982-D SM DT that is copper. Denver must not have been minting any more coper cents and somehow that planchet just sli]ed through.
Like I said, it would beike winning a mega jackpot for a quality control person at a mint to discern it wasn't zinc
