Looks like a candidate for making a deeper pan - if someone has a donor sump - or maybe just saving the baffle & scrapping the rest.
I'm thinking on your other items, around 40-50% of retail, or if blemished, in the $10-$20 range.
A lot of stuff comes down to how long you want to wait, and whether someone has a need, right ?
FWIW, I took a bunch of clean old stuff to the swap meet at the local track (Firebird Raceway, Boise ID area) this past Spring - sold maybe 20% of it (all of it was priced cheaply).
I considered the thing as entertainment & yukking it up with folks more than being worth the effort.
A packed-to-the-gills SUV yielded maybe $200.
