The obverse lettering listed is wrong. It doesn't says "IL ANO TRIVNFAL"; it says "II AÑO TRIVNFAL". There are several and deep differences between the meaning of "ano" and "año" in Spanish; and of course it couldn't be the 49th (IL) triumphal year in 1937. I've tried to change it, but it's locked.
PS: In the same way, it would be nice to change "ESPANA" for "ESPAÑA".
