I've got a mint, collectible condition Noct up for sale. This legendary and out-of-production lens is hard to find in this condition. There are no marks on it and everything functions perfectly. Just a couple of normal dust specs inside. The last mint Noct sold for $5,799 elsewhere, but I'm not even pricing mine as high as currently listed ones.
I have over 500 transactions on the big site with 100+ feedback, so feel free to check me out.
I'm listing this lens here for $4,295 shipped to the continental USA. International buyers will have to pay all shipping and insurance costs using a company that will fully insure it.
