acid will react over the entire surface of the coin and not just on the high points, thus it will eat away at it at the same rate.
this will explain why there is some detail on it.
If you look closely at the pic coin on top of coin you will notice that the detail is not a high profile like on a normal coin but relatively flat.
the difference in thickness in the planchet can be explained by the way acid eats coins, they tend to bubble from one side and the other side stays thicker.
Either way this is definatly not a mint error

sel, sap bit of help please.

Ok, the one planchet is out but I still feel acid would eat the face like a post note long ago about the faceless $1 on ebay if anyone else remembers

and why couldn't it be a mint error as we know they make mistakes
Rest in Peace

The thickness of the plancet is too thin. If the difference was caused by acid surely the whole of the detail would be removed yet both sides still have a large amount showing.

Acid removes from all dimensions equally. If it takes 10mm off the diameter, it takes 10mm off the peaks of the designs and 10mm off the valleys, so the design is intact.

Unlike wear, which takes 10mm off the high points and nothing off the diameter or the valleys.
Rest in Peace

If there's an explanation for how something could be done outside the mint, we must assume that's where it happened.
