I read up and saw several different instances of errors, but I could not find a thing on what I came across with my usb microscope. I attached some pics and enhanced them to sharpen the detail. Took some with the microscope and managed a few through the loupe and my phone. Looks like an extra pair and a half of windows. Anyone? DCam13
The doubled dies that have been reported so far occur primarily in the overhead arches. Very difficult to photograph. This looks like it took a hit.
Thanks for your input, CT Peeps. I'm getting better acclimated on definitions, but is PMD more like something happened in the facility, or it got dinged after put into circulation? Could technically mean either one, but there seems to be a pattern to the damage vs. a random scratch or notch like you'd seen coin roll hunting. There's a definite substantive shape to the bottom box especially, and what drew me in to ask you guys, is the definitive vertical line down the center of the square to match the windows of the back left part of bldg. Even if it is considered general "damage", it's the most interesting damage I've found so far on a coin. I think I just need to study up on the scope of what PMD can include. DCam13
There is no way of being 100% sure how and where the damage occurred. The only thing that is sure is that it did not occur during the minting process. Chris
It doesn't look like it could be the hit from a "reeded anything". Besides, how could the edge of a coin hit it with sufficient force to make the second mark? And, I don't believe that two reeded coins could have caused these marks separately at the same time. Yes, something fairly heavy probably hit the coin, bounced slightly and hit it again. That's my opinion! Chris
i agree with paddy, looks like bag marks, you take a bag of a thousand quarters with quarters stacked on top of each other and drop it in the back of a truck, the quarter thats laying parallel to those that are stacked will take hits from the reeded edges and will look like the OP's coin...
They are so specific and pronounced, though. Clean. I'm sooo new to all this, so I appreciate the feedback. I can't see how the weight of anything like you described would make such cleanly cut shapes and not damage or scratch any other part of that side of the coin. Looks curiously like one/parts of the hundreds of windows all over the same reverse of the coin. I didn't think it was a question. I likened it to the times you see a rogue number from a date somewhere totally away from where it's supposed to be. Or a duplicated mint mark somewhere else on the coin. Thanks, ken454! DCam13
You have to keep in mind that the details on a coin are the exact opposite on the die that made it. If the detail is raised on the coin, then it is recessed on the die. If there is an anomaly on a high point on a coin, then that anomaly is in a recess on the die. If this is true, how did something happen down in that recess that could possibly make a dent where it shows on your coin? If it were a extra window there, it should be raised on the coin, not indented.
Great point. Being this is 99.9% new to me, I hadn't thought of that (among other things) either. Thanks for the explanation. I hadn't fully processed a previous explanation of it being the grooves on the rim of the coin, but it clicked with your explanation. (The idea, at least) Details vs. the recess of die and vice versa. Nice.
Look very closely around the edges of the dent. There is a good chance you will see raised metal around some of the edges which indicates that the coin was hit. When a coin suffers a big hit, metal is displaced. Some of it is pressed into the coin, but some of it is going to form a raised rim. Take an objective look at the damaged area under magnification and look for a small lip/ridge. If you see it, then it was hit. BTW: The ridges don't always show up well on pics
