Glue - as mailed in a promo envelope for some product or company. If not that, it's still glue from something - it did not leave the US Mint like...
Mornin' all - the OP's coin is machined - grinde off on the reverse side. Not a uniface strike, of any mint error type at all.......
I agree that if that area is into the coin, it's a bad gouge. My reply was predicated on the OP saying that it's raised, and that the photos...
Well within Tolerance
Looks like a 'filled die' - grease or some other machinery oil was on the die, which prevented those design elements from being fully struck up....
What do you see in the top area of the '7' that looks different?
Still too washed out to see the natural surfaces. Based on what I can see, if it's raised, it's a pre-lamination 'bubble'.
The reverse (at least) has been heated, which causes the raised surfaces on the clad planchet. Not an error, all damage, including enviormental...
If it's raised, it could be an occluded gas bubble (pre-lamination) but the photo is actually too washed out, and too close. Can you take another...

The dimes are all environmental damaged on the surfaces; not errors of any kind. sorry.....
The 'o' of oF is weak because it is opposite the Bust of Lincoln - when struck, the metal flows into the larger Bust area of the die, making the...
DW - your dime has environmentally damaged surfaces - corrosion. Not an error coin of any type
Sorry, but your info in the above post is incorrect. I've been to the Mint - and as I posted for you earlier, US Mint tolerance is 27 degrees -...
It's well within OMT - Official Mint Tolerance. So it is not an error coin ... period As mentioned, because it's your coin, you can think...
Based on the photos, especially the close ups of the surfaces, it's been lightly acid, or chemically treated. It's not on a rolled think planchet...
I think you might be confused a bit - Your 1931-D Cent is worth what a circ. 1931-D cent is worth. I said that it has no premium as an error...
One of the prior posts said that looking at your mirror photo, it's about 15 degrees rotated. Even if it's 30 degrees, that's the same as 27...
It's posted on the Presses at the Mint. Took a photo of it when I was there about 10 years ago for a special Floor Tour of the Philly Mint....
US Mint tolerance for Rotated Dies is 27 degrees. They are not collectable until the rotation is a minimum of 45 degrees (when flipped over, the...
