Well while doing other things besides going through my grandpa's coin collection I noted this quarter with a lovely crack. what say you?
The die cracked from fatigue. When it did, it transferred a representation of the crack to the coin. If you look closely, you will see that it is raised above the surface because metal flowed into the void when it was struck. Chris
That 'smaller pressed circle' is actually counting machine or crimping machine damage. It was not a part of the minting process.
@Lyrics Very nice find! I agree.. That was caused by a Break on the Die itself and not on the Planchet. I believe it to be a Bi-Level Die Crack Here is the info with pictures - I want to share this webpage with you - http://www.error-ref.com/bi-level_die_cracks_/
I do not believe really anything worth mentioning. You would likely lose money in fees for the little above face value you might get for it. Die cracks are more common than you might think, as dies wear out cracks appear and then shortly afterwards they switch out the dies. That said, they make tons of coins in the time it takes to notice the cracks appear. I have one state quarter type where I have many different cracks from different dies. They are more minor than yours but I likely couldn't sell them as a set for much above face. They were fun to look for though.
