Having a hard time understanding why this coin weighs 2.66 and has an entirely different ring than any other coin I've came across including silver and gold. The coins appears to be the same as the rest of it's years except it feel so much lighter and has sharpened edges on letters and Lincoln memorial.

Photos would help. Front and back of whole coin plus one along with another coin. Photo of edge of your coin and another would also help.

Images a no help. But the weight is a clue. In 1971 there were probably no planchets in the mint that were steel. But if the coin is thinner, it is probably an acid dipped coin. That evenly removes the thickness of the coin. They used to do that in school and run the cent through a vending machine and get a soda back a few years ago for 10, instead they got an altered cent to give them one for one cent.

Note how the edges show the thinning. The best way to tell is if the rim is missing, and the coin is smaller around (more like a dime size) then it was normal and was altered somewhere down the line. That is what I feel this is.

The coin on the right appears to have been as acid washed



The coin in question is the one with sharper detail.
I have a question so does an acid wash make the LMC sound like a Canadian penny?

The edges seem to have a much shinnier look than any usual 1971. As if it's brass plated.
Another question of mine is the type of patina it's gathered in the years. Almost seems as if I can easily remove the layer and it would shine bright. Not the norm from what I have seen myself. Where they making any brass plated Penny's in 1971?

Doesn't really look like a cent that has been acid soaked long enough to remove that much weight. I suspect a rolled thin planchet.

Closer images would help more. If the devices are weak, I'd agree with what Condor101 suggested.

Not struck on a Liberia cent. At 18 mm the Liberia cent is almost exactly the same diameter as a US dime. A cent stuck on a dime planchet always shows a noticeable missing of detail around the edge especially if the planchet was not centered in the collar. Your coin shows full rims.

I do see a bit of a weak strike on the designs. So it might have been a thinned planchet. Seeing the image of the edge you can see that there is a coating of environment issue on the coin.
