Just a piece of mint goo

Found this stuck to the surface of a new quarter it was not struck into the coin. shown on cent for size
It was a solid roll from a solid box so I would guess it is from the mint rather than an outside source.
It looks like hardened or dried grease with a bunch of small metal fragments with an overall bronze color.
It looks like most of the fragments are copper.
I know this is kinda boring...... but it's not about a Silver Eagle

Thank you @ifthevamzarockin for posting that interesting “nugget” thing and not a EHRP thing.
Fred probably knows...
Cool!
It looks like a "Meteor".

Interesting....looks like an agglomeration of metal shavings/chips that accumulated in the machine and finally dropped onto a coin....Cheers, RickO
Hmmm 🤔 will PCGS grade it? If so what type of gasket will they use. It’s quite small

Is the coin available to maybe match the surface,
and see if it started out soft?
Could be grease, or someones dried beef.LOL
I found jelly in a roll, Fresh also.
Ya. Ya. ...A coin roll...
What? True and sticky.
Does it stick to a magnet?

Didn't try.....can try after work
How old is it? Will it CAC?

This is an example of a common soft residue found on 100% original coins - usually from 1950's to 60's. The darker residue often contains microscopic metal flakes.
The more commonly seen residue is clear and soft as on one half of this image. Usually the clear "stuff" does not show any inclusions.
Undipped/uncleaned examples are usually found in bank wrapped rolls of Franklins', Washingtons', Roosevelts', and Jeffersons. Look for it at the rims. It comes right off with conservation.
Is the photo of the Rev. of the Cent WITH the
crud on it Before you removed it?
If so, please post a photo of the reverse after
the crud/gunk was removed.
He wrote that "it was not struck into the coin." That's too bad.
I asked because of there is a depressed area
where the crud was lifted off, then it might
have been struck like that (no design, I know)
If it were not 'stuck onto the coin', then the
crud is from other counting/rolling machine
crud, and and it's not part of the minting/striking
process.
The crud was found on a new quarter and it left no mark on the quarter. shown on cent for size
Sorry I made that confusing.
In lower lighting conditions it looks dark, almost black. much like the example Insider2 posted on the 1959
In brighter light you can see the metal flakes and it looks more bronze or copper colored.
Nice item. Put it into a 2X2. I was given my example from a collector while pre-screening his BU original roll at a coin show.
OK, thanks for the clarification.
It's not an error coin struck with the gunk on it;
it's sourced from something else after the coin
was struck.
I have a dime that is "struck-thru, with retained mint schmutz" somewhere. Got it in change at a coin show concessionaire, actually.

Agree. Coins with traces of Mint grease or sawdust inclusions are not errors. It's the way they came from the Mint. Nevertheless, I think both are interesting.
@messydesk
Is mint schmutz the same as goo or did I get my numismatic terminology wrong again?
You're confusing schmutz, goo, and gunk.
Let's just call it schmutzum, and leave it at that.
It's funny, I seem to have that same "gunk" on my car when I forget to wash it.

My 1986-vintage Graebener coin press (Denver Mint surplus) was covered with blobs like that.
They were particles of copper and nickel, bound together into small lumps by grease and/or oil.
Thanks for the reply @dcarr
@ChrisH821 Not magnetic
If this means I can get PCGS to put "Struck Thru with Retained Schmutz" on a slab, I'm good with that.

Goo is gooier than schmutz. Not to be confused with "hunk of crud," which came up in a discussion of artifacts of the hubbing process recently.

We used to have a bottle of Nickumpucky that would clean that right off most anything.
