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

Mine is stereo, not mono, and I'll check it out and take notes after my granddaughter opens it on xmas eve.
thanks to everyone so far.  the album has been in my possession since July of 1967, so geoff's input isn't appropriate.
OK:  I have checked all the markings on the record and jacket.

I will check all the resources the helpful responses have indicated, but here's the info I have:

It is made in Great Britain in 1967PCS 7027On the label it says YEX 637, but on the vinyl, 636.5.  The letters HTM are (what looks to be) etched on the inner circle of the vinyl.
I have only played this a few times; it looks like brand new and plays beautifully.

Any ideas?
