Is Nakamichi Receiver 1 and CD Player 2 still worth enough to try and sell?

I am original owner of Nakamichi Receiver 1 and CD Player 2 purchased back around 1991 - 1992.  I stopped using them a number of years ago so unplugged them and put them in storage.  I recently plugged them back in to see if they still work.  Receiver 1 seems to be fine though bottom 10-20% of LCD display no longer displays.  Everything else seems fine, played both AM/FM output to speakers.  When I switched input to CD player, the CD Player 2 seems to have bigger issues, it will no longer play a CD when I hit play it tries to go through the motions to start up and then just stops.  No audio comes out.
So my question is what to do with them.  I'm trying to clear out space but just not sure of value given their age.  I reckon the CD Player may be worth extremely little given the issues but receiver may have some decent value looking at ebay and other sale sites.  If not I will just drop them off at the local E-waste recycle drop off event.  Anybody else have experience in trying to sell similar (or buy for that matter).
