I have "inherited" approx. 600 7" 45 RPMs

Thanks for the response. I have more than 600. I am willing to split and sell individually, but I see this could be a project. The records are not from a Jukebox or anything. They are from my Uncle's collection when he was younger..perhaps he played them a few times each. They don't take up much space as most are in about 8 or 9 45 RPM storage boxes, which are about 8"x8"x 5"each. If they are not scratched and clean, I suspect they will be somewhat desirable for an owner of an old Jukebox...LOL
Thanks for the responses.

Any place I can view titles you have for sale?

I think their value will be greater to collectors than to audiophiles in general.

Getting the best value out of them as collectables will require an investment in time and research.

I am not an expert but I suspect what GEoffkait said regarding the types that are likely to be worth more is true.

I'd be interested in knowing what you have, once you have them all listed out.

I'd probably try to categorize them into groups representing relative estimated values. Once you've researched prices of all in each group to your satisfaction, you can put those up for sale.

Just based on #s, 600 45s from over the years in good condition generally is likely to have significant total value that might justify hiring an expert to help assess and maybe even sell that would work off a % of the actual sale.

IT really depends on your time and availability to do it right and how much you need the money today. VAlue will probably only go up as collectibles over time, so not harm in holding on to these until the time is right to sell properly.

It all depends on what it is...if it's 600 punk rock 7"s from the late 70 and early 80s they could be worth tens of thousands. 80s top 40 hits...pennies for each.

Okay. I have gotten through about 1/4 of the 45s. They vary in titles and range from the 60s to the early 80s. Here is a list of some of the more interesting (subjective?)artists:
Frank Sinatra
Paul McCartney
Paul and Linda McCartney
Rolling Stones
John Lennon and Plastic Ono Band
Steve Miller
Creedance Clearwater Revival
Eagles
Aretha Franklin
Elton John
Helen Reddy
Abba
Steely Dan
Bee Gees
Foreigner
Aerosmith
Diana Ross
The Tempatations
Jackson Browne
John Denver
Wings
The Eagles
Peter Frampton
Tom Jones
Stevie Wonder
The Isley Brothers
Yes
Herb Alpert
10cc
The Jacksons
The Jackson 5

I will make the list available either as it goes or after it is all finished. As you can see, it is quite a rang. I have placed a dozen or so of various artists. All play through. Most sounded good. I use an older systemdec IIX with grado cartridge.
