Value of mint condition first pressing of Sgt. Pepper?


I have a mint condition first pressing (I think) copy of Sgt. Pepper's Lonely Hearts Club Band.  Vinyl is shiny and plays flawlessly, jacket is shiny with few indentations, and insert looks like new.  Any idea how much it might be worth.  Also, any idea as to how much value something like this gains over the years?  I'm thinking of giving it to my granddaughter (age 4) for her to cash in when she graduates high school.
Any input will be greatly valued.Russ

Too many non record collectors over estimate the value of used records.

If the record is worth less than $50 it is not even worth selling.

You have to run an ad , pay fees, buy a shipping box, hassle with price, etc.

Very, very few records are worth more than $50.

Just keep your records and enjoy, or give them to someone that will play them.
In my experience, it's generally records from the 90s that were pressed in low volume that are now sought after by my generation of Gen-X'rs that are going for good money. Try to find a copy of Marilyn Manson's "Mechanical Animals" or "Antichrist Superstar" and you will see what I mean. Vinyl was the mainstream format in the 60's, 70's and into the 80's. The volume of pressings makes those albums worth less, certainly there are outliers on the older albums like certain pressing of Beatles albums going for thousands of dollars but they are thre exception in my experience.  Your milage may vary...
Yes but demand is the most important. I have super rare Jazz albums . One is in Goldmine for $800. The thing is the albums have no demand; hence no buyers for even $200.
