Reverse appears to be a doubled die reverse extra thickness with some separation lines and splits

In my opinion, from what i can see from the photos, this is not a doubled die. Some areas look like worthless doubling, other areas look like the strike was strong to the point where it could have broken through the copper layer. I personally do not see any additional thickness. The letters look normal sized.

For example, look at the C in AMERICA photo. To the north of that primary C is a faint ghostly looking C which is almost flat. It's not at the same height as the primary C. That look applies to most of the other letters and mintmark.

The working die might have struck this coin and due to improper maintenance or misalignment, the dies chattered or bounced, and produced a coin with worthless doubling.

Double dies are created when a working die has received more than one impression. Those impressions are sunk into the working die, so when the working dies squeeze the planchet (blanks) into coins, what is sunk into the working die is raised on the coin. Those impressions into the working die should be at the same depth, so they should be raised at the same height.

The impressions should be far enough off axis to be seen with the naked eye or, under magnification at no more than 15x power. Otherwise it may be considered minor.
