I'm new to the coin craze.  Immobile for 3 months, needed something to do.  Bought 10 rolls of quarters.  Was watching Youtube and it was talking about these quarters being produced at a crazy rate because of shortages.  It also said that there were some die cracks slipping thru.  These 4 coins were all in the same roll, which I thought was like impossible.  My AI said the angle of the 4 cracks on the bottom were all at the same angle and that the 4 cracks were within .079.  There were cracks on one coin on the obverse and the reverse.
