Very cool, was the cent planchet on top of the nickel
dollar planchet when struck to get the uniface obverse?

That "strikes" me as an extremely obvious error. I do wonder how it got out of the mint...

why is there nothing on the obverse? and what does uniface obverse mean?

My theory is that 2 cent planchettes were stuck together their combined thickness world be a little thicker than the expected thickness of a nickel dollar. 3.3 mm in place of 2.62 mm.
That would explain a well struck reverse with a blank obverse.

The coin is very thin, and almost the diameter of a 25c. Somewhere, out there, is maybe a 1971 nickel dollar with a full obverse, and a reverse with a matching indent strike...

Short answer: Occam's razor (the problem-solving principle that the simplest solution tends to be the correct one).
Putting any "mint sport" aside, the odds of a 1c planchet getting into the nickel dollar business strike presses are pretty remote, the odds to support your theory of two 1c planchets sticking together, and entering the same production stream, are highly improbable. It is much easier to imagine a 1-cent planchet hitching a ride somewhere in the mint, getting fed along with a nickel dollar blank into the press and getting struck together. The orange-peel texture tells me it was struck on another blank, and a 1c blank sitting on a pure nickel 15.6 grams planchet getting struck by dies meant to create a dollar coin - would result in a very strong strike.

So would most then say this is an inside job and not an error. Usually an error is something that happens by accident and there was most likely intent to get a coin like this. There should almost be another numismatic term for coin "error" with manipulation.
