Many or the rolls I have searched have had these with an error on the nose. It appears part of his nose came off on one coin, and imprinted a 2nd nose (??). Not sure really. But I have about 30 of them so far ranging from just a small indent to what you see below and a little larger. Is this from a lamination error of sorts? Strike though from part of the nose?
thanks. The microscope picture doesn’t show the nose too well. I have one shot I took with my camera that makes it look like a flap came off the nose.
If it's got depth it's a strike-through. But then a strike-through doesn't evolve over time, it's the same on the coin at all times, so I'm not altogether sure what you're describing, here.
Yes, it happens often to Jeffersons. On the outside of the pillars each side. Never said this was a Jefferson. Infact I think I have a couple of 09' District of Columbia quarters that have them on the end of the Piano. I will see if I can find a few on a Jefferson, and the 09 DC Also the Homestead quarters had these on the roof. Not full blown die breaks (snow on the roof) but a slight indentation.
Believe it or not, I have a many coin strike through progression on Sally Ride quarters. I'm not near home to take photos but will upload them in a new thread when I am.
yes it is indented. And they evolve. Each picture I took is different stages on different coins. I could probably photograph each coin and it would look like a flip book of it growing.
On strike-throughs, it is more than likely the opposite, where what ever is on the die (usually the obverse because the reverse is usually the hammer die), is breaking apart or getting smaller with every struck coin. Most times its a one shot deal so regressing of the strike-through is uncommon unless it is grease in devices.
I looked up die dent. And the definition does not fit. A die dent would show as raised on the coin. These are recessed. Which would mean that the die surface is raised, in the area. A strike thru would change the look of the planchet surface. A strike thru would be large at first and deteriorate as the material falls away from the die surface. I am still not sure what causes these. Maybe a small retained IDB that may or may not progress into an IDB. Here are a couple of photos of my 09 DC. The area in question shows at the top corner of the piano. Also shows a small IDB in the recessed area. And then a curved area below the M and B of Columbia. Two different coins. Anyone see the inconspicuous S, by the IA on the Piano?
Do you know what a strike-through is? I’m not being a smart-ass. If you know, describe how it could widen.
well there are many different types of strike-through. That is why I am asking about this one. I am stating the obvious that 1: it is incused. 2: it mirrors the nose portion that is missing in post five. 3: I am now up to 50 of these quarters with the same error. 4: the incused marks do seem to grow (or shrink) So we can rule out PMD. Obviously didn’t happen on the hub. Something had to have happened to the die, or something became stuck to the die in the minting process. Could have been grease. Could have been part of another coin. I am not sure. It may not have grown, it may have shrunk. If it was a large chunk of grease, it could have slowly been eaten away on each strike.
Grease would change the look of the surfaces that were struck thru, these don't so you can eliminate a strike thru.
well that is why I am asking. Here are more angles. There also appears to be a part of the clad pushed up to the nose, or die chip, or who knows at this point. Here are the best pictures I can get.
