I've found these two in a recent copper lot. Granted, most of them are corroded but I think I have found something quite interesting:

Sorry for the bad photography but the rotation looks about right. This pushes the limit of the later year error coins that I have - I was thinking that by 1870s such error coins would be quite uncommon???
Anyone else with such rotation error coins minted around this era or later? I know there were a lot more rotation errors with Soviet coins but not with the late Imperial coinages.
Very interesting, indeed!
Some of the gold and silver coins of Nicholas II have rare varieties where the reverse is rotated 180 degrees relative to the obverse. Nobody knows why for sure, but perhaps it was done by foreign (European) mint workers who thought that was the way coins had to be minted (because they were done like that in France, Germany, etc. ...

). However, I am sure that there were also occasional error strikes such as you mention.
How did you manage to find
two of these in one lot?? Was this in some collection of error coins?
