Medal alignment [Risolto]

Hello all,

I recently picked up a 1959 50 Centimes coin from Belgium.

https://en.numista.com/catalogue/pieces1239.html

According to the notes on its Numista page, one of the versions of this coin is distinguished from the others by its "Medal alignment". I'm not sure what that is and am hoping someone can offer me a some details.

Thanks!
RJ

Medal alignment means that you flip the coin left to right, and both sides show the right way up. Coin means that you flip the coins top to bottom and the sides display correctly.

Thank you very much nthn!
