1982 P Double Quarter?

Thanks for the info! Coin collecting for many years but recently started learning about errors and I have so much to learn!

What may appear as doubling to you is actually the die breakdown. When the die was fresh the devices were normal. Just as a senior develops wrinkles, a die starts to break down. The single squeeze dies use a lower profile height. So when they start to break down they look different than the older die wear that were seen for hundreds of years on the multi hub die process. Here is an example of how the Memorial dies started to show die wear back in their day:

Note on the MDS die state that edge nearest to the rim is starting to round. (sharp in the EDS die state) Then they rounding continues with die wear. First that the edge that is closest to the rim. Then in the VLDS die state it really starts to break down. So with the single squeeze dies with the lower profile (shorter height of th devices and bust, the wear sarts showing more at first like a separate mark on the side closer to the rims shortest direction.

So while each die formation has it issues, they are all affected by metal fatigue as they age. (as all of us do also as we age)
