For Sale [SOLD] Nikkor 50mm f/1.8 AI-S Lens

[EDIT: it's been sold]

This lens came with my Nikon FM3a kit when I bought it. I already had a 50mm lens for the Nikon. It's lightweight, task-sharp and, most importantly, small. I do not think it needs an introduction. Selling because

a) I do not need two nearly identical lenses
b) I am mostly shooting medium format these days

No haze, no fungus, no nothing. Comes in the original box.

Asking $80 plus shipping ($12)

Oops, fixed the price.

Hope you don’t mind me asking, but how did you determine the price? I’ve got a bunch of camera equipment that I’m trying to selling and trying to figure out the best way to do it -here vs ebay vs craigslist, etc etc.

Also, I got one nearly identical, except it’s the f/1.8 with no ‘s’ after it. Do you know what the difference is?

Thanks!

OP here: I searched "completed" eBay listings for lenses in similar condition, then subtracted 20% to sell faster.
