It's a chemically improved formulation of penicillin as noted below. (reference cited) It might be the fifth compound tested, hence the Roman numeral V, or perhaps the various compounds investigated were listed a,b,c and so on. It was probably a useful experimental nomenclature.
Penicillin V potassium is the potassium salt of penicillin V.
This chemically improved form combines acid stability with immediate solubility and rapid absorption. It is designated 4-thia-1-azabicyclo[3.2.0]-heptane-2-carboxylic acid, 3,3 -dimethyl-7-oxo-6-[(phenoxyacetyl)amino]-, monopotassium salt, [2S-(2a,5a,6b)]-. The empirical formula is C16H17KN2O5S, and the molecular weight is 388.48.

The letters in Penicillin (as in V and G) designate different molecular forms of the drug.
These penicillins derivatives are in synthetic form produced by altering the original molecular structure of penicillin and are differentiated by their structure on the end of the penicillin molecule.
