1996 Penny .what Would You Call This?

I do not know how the images could be more descriptive. A mountain range on the obverse running from SSW to NNE that does not affect the rims, with a corresponding effect on the reverse that also does not affect the rims. Clearly the strike shows more pressure on one side than the other but not warped. I bet it lays flay on either side yet one side is thicker. The warping that was referred to is descriptive of the mountain range that is evident on both sides. Not that the coin itself is warped. I see no evidence of that in the images provided. How many angles must one observe?
This is an interesting anomaly and the OP deserves a reasonable explanation from those of you more knowledable in these matters than themselves.
If you have no reasonable explanation, just say so. Do not blame it on poor images and and misinterpreted terminol
I suggest the OP send the coin to another member of the forum that is more knowledgeable. Not a TPG as most suggest. Could they not send it to a fellow member for an in hand opinion for the cost of postage and get a definitive opinion rather than a series of criticism and speculation.
I have noticed that many new members have been responded to with condescending and sarcastic responses to the point of being made fun of for their obvious lack of understanding.. How much are you helping when you respond in this manner.
It looks like an interesting coin to me. But most of you tend to think it is warped,heated, melted. Well why are the rims Intact? Do the edge images look bent,warped, or just thicker on one side than the other? You either know what is going on or you don't. If you are not so sure than say so.

Could this be a lamination problem with some type of off gasing as it cooled?

Silviosi, as an example of my observations, I would like to direct your attention to the recent post of a brand new member seeking the advise of the well respected experts here. Specifically, the post made by new member "notreddie" posted on 12/30/2021 titled "1981 D Penny with Buffalo over Lincoln".
Please observe the many replies to this new member by several of the well respected experts making fun of the 0P description. These sarcastic replies contribute nothing to the subject and only serve to confuse this new member even more. Can you be sure that this new member is aware that others are just having some fun? The question at hand then becomes a discussion about animals while "notreddie" still has no reasonable explanation to their inquiry. Replies that contribute nothing to the question and irrelevant serve no educational purpose other than to increase one's "posts" on this forum. It is quite probable that this new member does not return.
I have seen this many times throughout this forum and find it insulting at times. I am sure many have a good laugh though.
