While there are some noteworthy differences in other denominations of 1988 and 1991, especially notable being 20 sucres, where newer drapery on the CoA is indeed performed different then the older one, this subnumber is not correctly assigned in my honest opinion. Writing this post since entries are separated still. The dies are clearly not the same, but… Below are rectangled CoAs of 1988 and 1991 - the older one indeed is smaller but to a what degree? Please consider the lighting as well (for the font of D on top for instance - it's the same) Much bigger difference is in 50S CoA between the years - documented here on numista, but still not separated of course for a good reason.

Let me know your thoughts please
