ATB Coins With Mule Characteristics

Nice closeup images but it is usually helpful to add full shots of the obv. & rev for context.

Looking at the die flow lines on these images, yours appears to be a later die state coin which can affect the surface of the die.

I hope you don't mind but I took your image, rotated it and added a yellow line that looks like an incuse line parallel to the left side of the "A".

a)Hard to tell if this might be on the die or just a contact mark that may have pushed up the metal in this area.

b)Caustic/acidic substances sitting on the surface of a coin can create an uneven pattern as it dissolves the metal.



c)Incuse designs on other coins can cause raised elements to appear.
(This next image shows a Lincoln Cent I found with some raised letters and designs that is most likely PSD from a foreign coin or token.)

anyone with thoughts on this newer pics?

definatly raised,, my dial indicator only lets me rear 4 places to the right of the decimal when I laid it out and tried to measure I can see a needle defliction decrease but its not anything more than guessable with the machine tools I have

Do yo. Still have this quarter?

Do you know what a mule coin is? It is a miss match of a wrong obverse from another series of denomination opposite the normal design. A few examples:


This one was declared not a legit coin:

Most of the time they are on a single coin, because someone is playing around at the mint. (Stuff that can get them fired and put in jail for) other times there are several of these all created by the same prankster at the mint. But that is what a mule coin is.
