The stewardship of wealth is often transferred from the foolish with too much of it (buyer), to those who actually need it (seller). Money is to be looked after, not squandered on guff. Now, if it were a known fact that this investment could be sold on at a profit, and said profit could be ploughed into something to help others, or feed and clothe them for years, or keep the lights on... well that's a GOOD idea. To buy it "just because" and have it stagnate on a shelf, well... no words.
My first thought is I must be getting old. My 2nd thought is are these really that rare? OK - it's NOS unopened box, but surely it's not the only example existing?
Do a quick search on ebay, lots available for <$100.
The value is the sealed box.
For the sake of a shrink wrap machine and the correct type of film, and the potential profit, I'd be resealing them for the chumps to purchase; it's not like they're gonna open them!
- in fact, a nice big bar of soap could take the place of the device, as a weight proxy.
