Price of Turkish Pink Floyd LP's Needed!!

Dear Fellow Pink Floyd Fans,

Since I do not have the chance to find a price guide for the LP's in Turkey, I could not find the estimated prices of some LP's. I would like to ask you for the estimated prices of some collectible Pink Floyd LP's, which are published in Turkey. It would be more than great if you can provide me with that information. Below are the LP's of which I want to know the prices.
