Lot of 36 scrap hard disk platters for platinum recovery or art raw material

Description

Had a bunch of dead hard drives of various sizes, brands and models, and decided to scrap them. I understand some people like to buy the old platters and recover the platinum off them, and while that sounds WAY too much like work to me, I certainly won't begrudge you the opportunity if that's your thing. I have no idea how much platinum is actually on these, and make no guarantees to that effect; I know next to nothing about how that process works.
Shipping listed is the furthest distance from me in the continental US; buyers outside this area should ask for a shipping quote before bidding, or I will assume you accept all additional charges. Also, be aware I use eBay's Global Shipping Program for all foreign shipments, and I have no control over how much they charge for shipping.
