Are 33 records from 40's 50's 60's worth anything?

Generally no but it depends on the specifics and especially condition. On the runout there is usually an index number that you can easily lookup at places like Discogs and get a relative idea of value.

It really depends on teh condition of the disc and the sleeve, and the rarity of the album. Even a mint copy of the Broadway cast of My Fair Lady won’t get you as much as an orignial copy of the The Beatles Yesterday and Today with original artwork. .

Also old does not always=$. Even LPs pressed just a couple years ago can sell for hundreds while common LPs from the 60’s may sell for a dollar.

Worth is also determined by whether or not anyone wants them.

I’d like to listen to them.

Unless they are mint condition they are more nostalgia.
I am an audiophile and but and listen to vinyl all the time. Unless they have some deep meaning to you then I suspect they are not worth much or worth keeping

I assume you mean 33rpm records.

If so some vinyl records can be worth a great deal of money due to their rarity but the vast majority are not worth anything much.

Added to this the condition of the record is extremely important. A record which is in pristine condition will be worth considerably more than one in poor and scratched condition.

The old brittle 78’s are good. Take them out on a cold day and throw them like a Frisbee through the branches of a leafless tree. So cool…
