There is such a thing as a strike-over, but that involves a minor change in the original design on the die. Example: The original reverse design on the Morgan dollar contained 8 tail feathers on the eagle. Shortly after releasing those, there was a design change to the die for 7 tail feathers, and many Morgans with 8 feathers which had not been released into circulation, were struck over with the changed die, and this created a 7/8 strike over variety for the 1878 Morgans. As far as your coin goes, it looks like PMD to me.
the scalloped design under on the bottom of the quarter is raised, and the design under the wingspan is also raised. this just might have to be sent in to verify. I'm working on better pics, and if I get any that seem significant, I'll post them. this is probably a stupid question, but have you all tried to magnify x200 orx400 ?
I beleive the older 8 tailfeather dies were re-hubbed with the new 7 tailfeather design causing all the coins struck from the dies to have the 7/8 tailfeathers. The coins with the 8 tailfeathers were not overstruck with the new dies.
No question is stupid unless you mean it to be. With that said, the most I have used is 30X-40X. What you suggest would be too close, you still need to see things in context of possible die markers and the anomaly you are looking at.
i can see the anomaly without anything, and really see it with 3x. I just meant blow it up on your computer to distinguish the outline of it. been working on pics
This is as close as i could get to the outline of the design. We think it kind of looks like a bust. *Now can you see it?? Let me know.*
This is a tough one. It seems clear that you have stated the unusual mark is raised. Based on that, and assuming the mark is part of the coin and no sign of it shows on the reverse, my final answer is either a big die crack, or more likely, a strike-through of thread or wire (like steel wool). If the anomaly was concave, then I would agree with others that it is Post Mint Damage, but it is raised. If it was a strike over, it would more than likely show evidence of what the previous coin was as stated by a previous post. Either way, I say it is a keeper just for the apparent uniqueness. Also, if you run into anything else similar, you can compare it. Place it in a cardboard 2X2.
