So they're slowly rotting (I mean, not rotting but you know what I mean). It'd be wise to back them up digitally if better digital copies are hard to come by.
But a couple additional thoughts:
-
Whenever you actually watch one of them, put it back on the shelf backwards/upside-down. Wait up to six months. Anything on the shelf that isn't backwards/upside-down gets put in the 'don't keep' pile.
-
If you're looking for a hobby, don't want to keep them but don't want to toss them right away, you could play around with ... idk exactly you call it, but video mixing? A couple VCRs, some sketchy looking hobbyist tech from Etsy, and a capture card, and you can play around with multiple analogue video sources and noise introduction to make some cool as fuck visuals. Actually looks hella fun, it's high on my post-divorce distraction list. Use 'em till they're dust for this purpose or you get bored. If you want to squeeze more life out of them afterwards, there's lots of crafts you can do with old VHS bodies and tape.
Caveat: At minimum, if you have old VCR recordings, back that shit up ASAP. Old commercials and TV shows (particularly super local stuff) are of massive interest to a certain type of person, who would appreciate your efforts. This goes double for cam footage/recordings of live events.
