I have a collection of several dozen 78 rpm shellac records that I inherited from my father, who inherited them from his father. I have a turntable but it won't play 78s. Been wanting to check with my local university to see if they could digitize them and maybe take the originals as a donation.
I have also thought about looking for an old Victrola at an antique market and keeping them to play as a novelty, but it would really be just that.
