Selling a very rare album


Want to get your thoughts. I'm selling my album collection and I have a rare issue from Jethro Tull named "Hand in Glove" that only 500 were pressed according to disclogs and popsike. The album actually has paper glued on the front and back with Ian Andersons face with a slogan on the front and the song names on the back. It is a double album in mint condition. How would you determine or who would you ask how much something like this is worth?

I actually have a copy of this show on a CD.  I was big into bootleg trading in the early days before everything was downloadable on the internet.
I saw Ian Anderson about 7 years ago in Morristown NJ  My son called me up said hey Ian Anderson is coming to town let's go see him.
My reply was, You have no idea who he is ! As I remember my son running out of the room when I started to play Thick as a Brick :  )
Anyway we went. And Ian had absolutely no voice left, but could that man play the Flute!!
I was right my son really had no idea who he was, but he did enjoy the concert. There is hope
Bootlegs are best sold on fan sites of the actual artist. I would find Jethro Tull fan forums and go from there. Back in the day, Elvis Presley bootlegs were popular. Now that RCA has released everything under the son, including many soundboard recordings with their FTD issues, the values have dropped quite a bit. 
Discogs won't even allow it to be listed, presumably because of the questionable legal status of the bootleg.
Maybe you get more money if you gently erase "Hand in" and replace with "Smell the" instead. That way you would have Spinal Tap classic to sell :)
