10 Haléřů Czechoslovakia coin alignment vs catalog's medal alignment

Hello fellow collectors,

I am rummaging through my stash of circulated Czechoslovak coins.

I encountered a single 10 Haléřů 1977 with Obverse/Reverse coin alignment. I have 8 pieces of the same year with the medal alignment as is in the Numista. All other years I have in my collection have the medal alignment as well (about 50 coins).

Can somebody please take a look into literature (or their collection) to check if this was ever reported or if it's know for this coin?

Thanks!

Mine is medal alignment.

@rsirian1 Thanks for checking!

Not the best picture with mirror, I placed the “standard” medal alignment coin next to the one I discovered in my collection with the coin alignment ( it's not full 180°) but it's very close.

Medal alignment as well.

Medal alignment as well.

Thanks for looking @Sjoelund . I contacted some local numismatics' shops to check if they know about any literature on this matter for Czechoslovak coins, so far no luck.
