Could be worth sorting through, but might not be... 250 isn't a *ton* in NC world (which seems crazy to say LOL) but if it's 2014 & earlier, there could still be some gems up for grabs that are worth enough to mention in a sale.
If you want, the quickest way to get it priced would be to make an account on impress.openneo.net, auto-upload the source codes from the closet + safety deposit box NC pages - if you want to PM me the link, I'd be happy to look through the items on the account & let you know if there's anything of value!
