In Sacramento in the 60s and 70s, there was a junk shop on Folsom Boulevard, close to 35th Street near Alhambra, that sold old albums and 78s,, one record for a dollar, half a record for 50¢. Yup a broken half record for 50¢. He had piles of them. . .
He was quite looney... I asked him what someone would want a half record for and he said if they could find both halves they could glue them back together, , ,
Ha! That reminds me of a record dealer I used to know, may he RIP. One particularly obnoxious customer was trying to argue the price down on a dollar record; he only wanted to pay half that. My friend finally had enough. He snapped the record in half and handed the pieces back to the customer and said “now it’s 50 cents”.
