From 古期英語 peniġ, a form of penning, from Proto-West Germanic *panning, from Proto-Germanic *panningaz.
The plural pens possibly originates in collocations such as six penies which were pronounced as a unit with stress (largely) on the first element (/ˈsikspɛni(ː)s/, /ˈsikspɛni(ː)z/), making the unstressed final vowel especially vulnerable to syncope due to its distance from the stress.
