1964 Lincoln Memorial Cent With Ripple Effect

I'd like to see the whole coin, if possible.

If you notice the ripples on the obverse run sideways and on the reverse they run up and down also notice how the date liberty and the rest of the script seems to have been left alone and if we look at coins differently dose canada have their own grading companies and who decides if a coin in canada is an error or not is it the mint in canada that decides ya or neigh error wise and if canada decided it was an error why couldn't the same thing happen here is canada part of the numismatist society thanks for looking

Well whatever it was, probably dipped in acid, it is absolutely worthless and not an error.

I would recommend moving on from this coin.

Hydrochloric, sulfuric, or nitric acid.

Oh and for the blowtorched coin, you didn't properly do it. The flame should be moving and not staying in one place, heating up the entire front surface of the coin, not just at one place.

You let the coin burn too long. You want the heat to melt the plating, but not fully melt it and burn it off.

I agree with merclover. I understand that it is certainly neat to be exploring the scientific properties of the metal in coins, but you're moving onto a different aspect of science. This is a coin collecting forum, not a metal testing property forum.

Sure it can be fun, but as a coin collector, I would advice you to move on and continue coin collecting, find some neat coins, and continue searching, rather than experimenting with the coins and their properties. Well, that is if you want to be a coin collector and continue the hobby.

Hello everyone one quick note to silver coin,,you speak as if you have experience ,first that coin isn't even an inch around what makes you think I was doinging it wrong it's not too hard to hear up a penny evenly,I wasnt using a pencil torch and as far as holding the torch in one spot and burning the copper those were zinc cents except the one solid copper as you con see nothing happend to the copper cent but the zinc cents ,the copper never acted like it wanted to start sagging and to heat that penny evenly would make both sides sag the same direction not one side up and down and the other side sideways ,and the coin couldn't have been acid bathed because it weighs 3.1grams there is no copper missing ,and I think by the time you got a penny hot enough to melt that's exactly what's gonna happen it's going to melt,so I dont think I did it wrong and you wouldnt have any idea how I did it or what I used to do it,I'm not some 13 year old kid playing around with money nobody seemed to be willing to show me an example or try to duplicate my coin everyone had great ideas of how this happend but nobody could show me so I experimented my self I may not be the greatest or even considered a good coin collector but I think I know what an acid bath or heat or whatever else everyone said was the cause still nobody could show me and make a believer out of me sorry but it just seems like you like everyone else has the answers but not the proof to tell me I did it wrong and never experiencing it first hand yourself explain exactly how I should heat up something less than an inch around how can anybody learn anything if nobody can show you an example of something that they witnessedpersonallt thanks everyone

Coop already showed you another example, and no ones going to recreate it or tell you to because again, that's defacing US currency which is illegal.
