My guess is that the apostrophe evolved as a wildcard character representing "e" "a" or "o" (since Spanish plurals end in -es -as or -os)

Link - Phil / Lorena Phil: the same link posted for another question has Cajas " 'S " (at the top).

I don´t know if it makes sense, but I asked someone who has medical experience as I certainly don't, and the person said the Caja x 10 'S, Caja x 20 'S, 30 'S, etc., and that the "S" meant it came in tens, twenties, thirties, or whatever, if that makes any sense or is of any help! (as in this example).

Thanks. That does seem to support my suggestion.

@phil that makes a lot of sense, apparently 3 different versions can be used see here:

Could the S be the English plural suffix with what we Brits call a greengrocer's apostrophe, ie one that shouldn't be there? So they're calling the packs 14s and 98s? Just a guess.

Andreas THEODOROU (asker) Dec 17, 2012:

the document is Colombian Spanish FYI

Andreas THEODOROU (asker) Dec 17, 2012:

. Thanks for the answer but it's not likely because packaging is in blister strips

lorenab23 Dec 17, 2012:

Maybe? the S may stand for "sobres" see here
PROTOS CAJA X 14 SOBRES X 2 GRAMOS
