I found this one in a bank sealed plastic roll of Maryland statehood quarters. I know it is a type 1 blank but what I haven't figured out is what the bubble is from. Someone tried to tell me it was in a fire but as you can see there is no off color and the fact it was in what was new then roll makes me think otherwise, is it some sort of gas bubble? and does the bubble bring more value than just the blank itself?
You are showing both sides right? And that is a Type 2 with raised (upset) rim. Type 1 would be flat. It's some king of PMD - Post Mint Damage. That would not occur during the Milling of a coin. Blank or not.
It's a dent. There is no way to ever know how it got there, but I can assure you that it didn't come from the mint with that dent.
Im sorry yes type 2 I get them confused and yes that is both sides of coin. I wish I could get a better picture of it but the one side is a raised lump on the coin there is a very small indent on the other side but they arent in the same location if you were to flip
With clad coinage, bubbles are often encountered when the coin has been in a hot envionment (fire, oven, etc.).
If it were heat damage, one or both sides would be puffed out, it would not be depressed on the side opposite the bubble.
I'd like to say again this was found in a bank wrapped roll of Maryland state quarters it's possible that it is pmd but it wouldnt have been intentional pmd or else why would someone put it back in circulation instead of keeping for themselves. I still believe it is some sort of gas bubble from the formation of the clad itself because the indent you see on other side is really shallow and the bubble is rather large and they dont match if you flip the coin. Im not a error expert by no means but is there a chance that it could be a mint mistake other than the fact it's a blank.
Those rolls do not come from the mint. Ever. If you took the time to learn how coins are minted, you'd know that it can't possibly be a mint error.
I just took it to a coin dealer in the area he said it looked like maybe it was a defect in the sheet roll that was turned into a blank but was rejected when it got to the part where they go to strike the coin and some how it got into circulation. I'll probably send it in to a grading company I know I take the chance of it coming back pmd but just to satisfy my curiosity i'll send it in with others that I want slabbed.
I've never seen one like that, but this was my first thought as well (assuming it isn't PMD). It is not unheard of to have gas bubbles or occlusions in between the cladding layers. On a struck coin, this is often the cause of laminations. Again, I've not seen one before, but is possible that a pre-lamination planchet escaped un-struck.
No he did not but he is not an error expert just a coin dealer. but he is also someone who has dealt in coins long enough to know not to jump at a coin he doesnt know enough about
Have you weighed it? I'm with whomever said it was in a fire, not a house fire, but a torch fire. I've got several planchets and none are as grainy as that one. Also there are flow lines around those marks you.pointed out but they aren't caused by metal movement from a striking, they appear to be from induced heat.
The problem with that explanation is what would cause a RAISED lump in the strip that could survive multiple passes through the multi-ton pressure of the steel rollers rolling out the strip? If something could have survived without being crushed it would most likely have poked through the surface of the strip, plus it would not be a small roughly circular lump. The roller running over the object would either A not rise up pushing the object ahead of it and tearing a hole in the strip, or B rise up over the object resulting in a thickened ridge running across the width of the strip. The only thing I can think of that could cause a raised lump in the strip would be a chip out of the finish roller (like a die chip). But the surface of the lump seems too smooth for that. Plus the strip would have a regular series of these lumps running along its length that would almost certainly be noticed and the strip rejected.
