Pinball is a great hobby my suggestion would be to fix 'em up & play them.
If you do decide to pass them along take some pics of backglass , playfield , cabinet and for the Solid State Speakeasy the circuit boards.
If there is a battery on the MPU circuit board cut it off and hope there is no corrosion ... if there is corrosion simply list it as such (pretty common problem unfortunately)
Any repairs may not help with the sale should you go that route but again it is an enjoyable hobby and a lot of good resources available to assist you with them
Good luck with your decisions & welcome to Pinside
