What do you think happened to this 1985 penny??

It looks like trapped gas bubbles or something.. what do you make of it? the coin is the same way on both sides.. really odd looking





thanks for any and all input..

reminds me of a nestle crispy chocolate bar!! yum.. lol

 

Someone walk on it with golf shoes? Used as the 'bullseye' on a dart board???

 

Your right it does look like a Nestle Bar factory got ahold of it. I really don't know a whole lot about coins but I am sure someone on here will know or have an idea. I am wondering if it is because of some kind of acid. But it looks like all the little bubbles are risen. If thats the case maybe something happen with the metal while being made. Like I said I really don't know a whole lot so you would be crazy to listen to me. What ever it is, I would hold onto it.. worst case its a good conversational peice. Could be used to help bring the new generation of kids into the coin world. Tell them Willey Wonka made it or something.

Cool coin, thanks for sharing!

 

the little bubbles/blisters are risen on the coin.. i kinda thought acid too but then the coins color would be altered in some way i would think. i don't know either honestly.. hoping for some explanation that might make sense..

 

Looks like a case of chicken pox's.... isolate and feed the fever !!!!!!!

 

Cute

 

PMD. A total guess as to how it was damaged: might be from the sparks off of some type of welder, but I'd say the chances are low. A slightly better guess is it was heated in a way that blisters formed, between the clad layers. Several of the bubbles look to have burst and collapsed. Maybe someone threw it in a microwave (killing the microwave in the process).

 

I think the zinc mix was off, lots of gas bubbles in it. Then, the cent somehow got heated to high temperatures, but not high enough for the zinc to melt... so the gas bubbles expanded and pushed to the surface, and what you see here is the end result.

 

First off, plating adhesion was a major problem for Lincolns of that era. I have seen many coins whit that many blisters, but they were all tiny. Any acid or other corrosive would result in major damage to the zinc, so I see no evidence of that type of PMD. (Zinc is much more reactive than copper.) I would guess the coin was in a humid area and it propagated the larger blisters. That is not wet (i.e. no liquid), but very high humidity.

 

Looks like the coin had a little chemical rinse. Possibly on purpose, possibly an accident. We may never know!

When i was little and doing a project for school, i left some pennies in different liquids with high acidity levels and some looked similar to that.
But mostly it just destroyed the outside of the coin/the newer pennies that were barely made out of copper./
just a possibility though.
hope it helps

but of course i was little than and i was just throwing them in high acidic liquids
~shrug~
who knows, either way it's pretty cool

 

I surely don't know, but it's wild to look at! the coin is much darker in hand.. my dino-lite cast's a bright light when used.. I have no idea how to reduce the lighting in my pictures..

 

Zinc rot 1983-93 LMC are well known to have that.
plus it may have been laying out on a parking lot-or ground?

 

I have seen one that was put into a flame look like this. I have read they make a popping sound when put under flame. Guess you could try it if you want, but I would wear eye goggles to be safe.

 

never thought of that, jello's right.
it could have been laying on the bumby tar and could have gotten ran over a few times

 

Doubt it, that looks like metal was added or pushed out from the coin, not like it was ran over.

 

if i was abe i would take my self down to the doctors very quickly, looks like he may of caught some thing nasty probably from one of those walking liberties he hangs around with. i never did trust those girls, walking around exposing them selves like that

 

Calum, may I ask, What the -

 

dont worry too much about it i was just joking.
