I was randomly looking in my error coin picture files to look for an error example and came across this Lincoln Cent from 1946 under plate blistering, but realized it's actually gas bubbles, since pre 82 Lincolns had no plating (I'll have to relabel the file). http://www.error-ref.com/gas-bubbles/ Does anyone else have any examples of other coins/denominations or pre-1982 Lincoln cents with gas bubbles?
@paddyman98 you might remember this from some years ago, when I might've posted it. My file says created 2014 and modified 2016.
Since the artists rendition on both sides are undisturbed and the obverse is as flat as would be uncirculated i have come to the conclusion that this is a result of gas .its very intriguing to every coin shop i take it to.what do you think????
Sir, I remember this coin, and the answer is STILL the same. Your coin has been heat treated and damaged after the mint. That's why it has that weird coloring on it. I've had tons of coins come through my hands that were exposed to extreme heat and that discoloration is the most obvious sign. It was exposed to the heat long enough to cause the gas to expand inside, without melting the clad on the outside. That's why there's no damage, because the ENTIRE coin was exposed to the same amount of heat, instead of it being poked by a hot rod or something. If you don't believe me, (safely) experiment with putting clad coins near high heat without letting them melt. Edit: your coin shows zero mint luster, because the coin did not leave the mint looking like that. Do you see the coin I posted above? Notice how it's UNC but has the bubbles? The coloring on your coin is the biggest tell that it was heat treated after the mint. I'm sorry you don't like the answer, but that is the answer nonetheless.
No.. It is not Occluded gas.. Not a mint error.. Just heat damage Not all coin shops owners are mint error specialists.
That latest quarter above is NOT the result of occluded gas bubbles - As posted above, it's been heated - that's what purposely caused the 'bubble'. Compare the surfaces of a normal clad quarter to your quarter - your coin is duller, a bit darker, etc. from the heating. It is not an error coin of any kind, I'm sorry to say.
@Colbyjayofbakersfield 1. No, that is not mint luster. 2. This is what mint luster looks like: 3. Yes, I am a scientist. 4. Whether or not I am a scientist has absolutely nothing to do with my ability to identify your coin as damaged. 5. Stop yelling at me (take off caps lock).
