because they have almost zero resale value.

Years ago when my grandmother passed away, I took her collection of 78s down to that record shop on the SW side of Chicago. I think it was around the 9700 block of south Western in the Beverly area, but the location is fuzzy nowadays. Anyway, it was the primo shop for buying and selling used LPs according to the Chiago Reader. Unfortunately, the owner said that even he had no market for music that old and refused to take them off my hands - even if I gave them to him for free.

I think my mom threw them away on the next trash day.
