Hello everyone again I'm here today to refer back to one of my early posts the 1964 Lincoln ce t with rippling effect,what I'm curious about is who is responsible for identifying canadian coins and their errors?because for some reason everyone debunked my coin as being a whizzed coin or heated or even acid altered,but what confuses me is why are there three known versions of canadian cents that have the rippling effect also,only in the canadian coinage these rippled coins are recognized as being error coins from the mint,they look almost exaly like mine,how can the canadian cent be recognized as an error but the u.s. cent everyone says cant happen,can anyone explain to me how come the canadian cent is recognized as errors but mine isn't thanks again  |

Interesting...I've seen this before but I don't remember what exactly caused it.
I'll let the experts answer this one

It has been dipped in acid. PSD. Canadian coins are determined differently than American coinage. For instance you can see a 1979 Canadian cent that they call doubled when the same coin from American coinage would be called Die Deterioration doubled. How do I know this, I have one of the very few specimens where all of 1979 is doubled. It is on the website CoinsandCanada. My name is attributed to it. It's not truly doubled. Edited by Jim0815

Looks like it was heated with a torch to me?  |

Ah right, I knew it was some type of PMD but I wasn't for sure which. Actually, yes a blow torch is the most accurate I believe. I remember, I've done this myself when melting down a couple of cents for experiments. They gained this ripple effect as the outer plating melted. |

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.

And again I am still curious as to what kind of acid would one use that would make the copper liquify then re solidify? I'm sure you must know what kind of acid I should be looking for so that I could try and duplicate this oddity again thanks for looking

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.

Please don't go deliberately defacing/destroying coins. And too, it's against the law to do so. Finding an acid defaced coin is just a ruined, damaged coin, it's not an error coin. As long as it's recognized as US coinage, it retains its monetary value. Move on, life is too short, and there's lots of cool finds to be had out there. |

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.
