Same Coin. Are These Errors And How To Identify.

I may see some die cracks, but I have no idea of what I'm really looking at.

It's a best practice to post a full image of both sides of any coin and add the date, denomination and other important information in the post title. These photos, while very detailed, don't give any impression of what your coin looks like. If you could post new images, it would be easier for us to give our opinions.

Please keep posting your question and images, but make it easier for us to answer your questions!

Other areas maybe die scratches. Any void on the die will leave a raised Lin or are. Die cracks, devices, design, even die scratches will show up raised on a coin. These are normal. On one image it looks like a hair on the coin. But you are just starting. There's a lot more in store learning about coin collecting.

What about the last to? The p mint mark?

From the images provided, they look like a normal coin. Rotate the images and get a close view of the area your looking at. If you are looking at the reverse devices on the outside edge, they are incuse. So if there is doubling there, it is Machine Doubling. The rules reverse from raised devices.
On raised devices, a doubled die will show an enlarging of the devices. Machine Doubling will reduce the size of the devices.
On incuse devices, the Machine Doubling enlarges the devices and the doubled dies are reduced in size. (Just opposite for the raised devices) On the outside devices on the reverse, 70% of these ATB Quarters show Machine Doubling. (mild/medium/huge) But no DDR's are found on the outside rim incuse devices. These dies are single squeeze dies, and the doubled dies are found on the centers of the reverse/obverse designs.
