2016 Harper's Ferry P Doubling?

Funny you post this. I have 21 different Harpers Ferry quarters that are all different. I'm trying to get the pictures together and will hopefully post later today. Note I don't believe any of them would be considered errors,just varieties.

Cory: On the ATB (America-The-Beautiful) quarters the reverse devices on the outer circle on the reverse are incuse (sunk into the coin) elements. Raised on the die, the slightest movement will alter the devices creating Machine Damage on them. This will enlarge them and make them look like a doubled die, but they are not? Because a doubled die has the doubling on the die. On MD this happens from a normal die, but the machine damages the devices mechanically. So they are not doubled dies, but often look like them. They can look like these:




The devices are raised on the die and the slightest die movement before or after can alter these devices. I see a bit of distortion on your coin as well. On incuse devices the ball game is just opposite the raised devices for doubled dies.
