1977 Lincoln Penny Obverse Lamination Error. Please Check

Sir, if you add something to anything it logically increases its weight. Not only a coin but anything ?

a lamination is usually a Missing piece of metal from a coin - thus losing weight
a retained lamination and a 'fold over lamination is when the material has not fallen off the coin thus maintaining the same weight.

Very curious about the weight, yes.

WOW.

I apologize, you are all right, it is not a lamination error. It can be either BONDED COIN or CLIPPED PLANCHET. If you have the coin in your hand you may clearly see that there is metal strucked to it. After consulting with ChatGPT the following came up:

When a coin appears to have external metal pressed onto it, the error is typically referred to as a "bonded coin" or "clipped planchet" depending on the specific characteristics of the error. These types of errors fall into broader categories of mint errors that involve anomalies during the handling and feeding of the metal blanks or planchets into the coin press. Here are explanations for both possibilities:

Bonded Coins
A bonded coin error occurs when two or more planchets (or a planchet and another piece of metal) are fed into the coin press simultaneously and are struck together. This can cause them to fuse or bond under the high pressure of the coining press. The resulting coin(s) will show parts of one or both planchets compressed together, sometimes creating a thicker-than-normal coin or a coin with extra layers of metal. This error can be dramatic and creates a very unusual and collectible piece.

Clipped Planchet
A clipped planchet happens when the sheet of metal from which planchets are punched out is misfed, and the punch overlaps a previously punched area or the edge of the sheet. This results in a planchet with a section missing, typically showing as a straight or curved clip. If another piece of metal from this process accidentally ends up being pressed onto a planchet during the striking, it can appear as if external metal has been added or pressed onto the coin.

Other Possible Errors
Foreign Object Errors: Sometimes debris or other foreign objects can get stuck on a planchet and get struck onto the coin's surface. This might give the appearance that external metal or material is pressed onto the coin.
Double Denomination: This occurs when a previously struck coin (of one denomination) inadvertently reenters the coining press and is struck again with a different denomination's die. This would also look like one coin pressed onto another.
Each of these errors is relatively rare and tends to be highly prized by collectors due to their unusual nature and the unique story they tell about the minting process.

Thanks a lot you guys have been really very helpful and again my apologies.

@ramon1604 ... ramon, the guys here are trying to help you... I came to this forum in the same manner, having searched a 5 gallon jar 40 year accumulated change, & had singled out about 400 coins as "errors" ... turned out, to my great disappointment, that none were errors, or valuable, just common damage that happens to coins ... If you had anything of interest, these guys would congratulate & encourage you further ... you'd do well to avoid sources like "chatgpt", or , whatever ... there's no specialized knowledge there ... seek the advise of knowledgeable, experienced folks who are willing to give you an honest evaluation...keep looking & keep posting, bring a sense of humor, & enjoy ...

@ramon, in reading through this thread, it has been a bit of a roller coaster. However, throughout, the majority of folks here have consistently deduced that you do not have a mint error here. I encourage you to hang around here, reading other threads to familiarize yourself with what different mint errors look like...and don't look like. You could also spend time examining the error-ref.com website. I would absolutely avoid asking chatgpt for answers as the algorithm is definitely steering you astray.

I don't want to lock this thread because I feel like the communication in this thread is still ok, but we are definitely starting to skate toward the thin edge of the ice. Please accept our communal opinion that this cent doesn't have a mint error or else jsut send it in to a TPG for slabbing and then please circle back with us the results so that we can learn from this mistake. Thx.
