This coin has a general bumpy surface that is more pronounced above Lincoln's head by the "WE TRUST" on the obverse and by the "E PLURIBUS" on the reverse. The L in "LIBERTY" on the obverse looks affected also and possibly struck too close to the rim. Whats up with this coin? It doesnt appear to be corroded.
Looks like someone's attempt at "whizzing", IMHO, but I could be wrong on this. Whatever was done, it's been messed with I can tell ya that. Phoenix
I vote for the bead/sand blasted. Never looked that close for copper, but that is what it does on stainless.
I recently found these 2 1980LMC's- check the Ripple effect etc - a little similar to the reverse bottom on your coin.- I sent both of them to Mike Diamond for a final determination- from his expertise, its post-mint but he does not know HOW it was done. Both coins weigh normal- for a 1980 cent- 3.10 grams. Amazing with what people can come up with I guess with too much time on their hands :whistle: 3 pics are from one coin and 2 others from the second coin- the second is not as pronounced as the first. The first coin really looks sharp- regardless of its post-mint damage
Perhaps its been through a fire???? LOL, good one Phoenix. Make sure no one tries to sand blast Stainless
We used to bead blast a lot of stainless where I worked. We did not do much copper. Copper was too easy to blow a hole in so we just replaced it. Does that make more sense to you?
I was making a bad attempt at a joke there (stainless the member...) I know what you were talking about, I was just trying to crack a joke (I think atleast one of them should be funny sometime, the odds are in my favor. ) Phoenix
Phoenix it was a good joke if you know stainless , at least thats what I thought of when I read it . LOL rzage
That was the outcome- Mike Diamond determined it was post-mint- not consistent with valid die deterioration he has ever seen, but he could not figure out exactly HOW it was done. I had all sorts of explanations on it over at the Coin Community Forum, from Lemon Battery Test to high powered commercial blow-torching to different acid treatments etc, yet no one really knows EXACTLY HOW it was done, especially since there is no weight descrepancy. They even contacted members of the metal club to see if they could figure it out- never got a response back. The coin is the exact weight for a normal 1980 LMC. No one has been able to even come close to duplicating this coin by any of the above means mentioned.:headbang: Unfortunately, you may end up in the same boat, but you never know, maybe someone has the answer, especially on how to make those ripples on both coins. Try posting your pics on the Coneca error forum site to the attention of Mike Diamond . It wouldn't hurt for him to see ANOTHER ONE out there. Good Luck!!!!
That is exactly why I said bead blasting. If done properly, it will not affect the weight. All acid treatments will affect the weight. Incidentally, another method would be walnut shell blasting. You say all methods suggested have been tried. What were the results when it was bead blasted?
Battery Acid effects... car batteries from years ago tend to leak acid around lead post. Copper cents were placed on lead post/cable to collect corrision to prevent cable from losing contact. The coin in photo probably came from Grand-pa's old Chevy. Ozark
Blow torching, lemon battery test, acids- I never said sand-blasting and if they did sand blast a coin, not one person has POSTED a coin done by that way or any way that comes out resembling this one. Maybe you can have a lincoln cent bead-tested etc, please post the results. I just want to see one coin that looks like this one after someone messed with it!- by any means at all and I'll :bow:.
Orange Peel Effect Might of been done during the Electroplating process. Not sure of the proper terminology. Electrical pulses begin to act like Radar/Sonar waves, given the look Orange Peel, due to the impulses. Like dropping a stone into the water and watching the ripples, :kewl:
