You never want to see the shrinking, wrinkling Crystal Mounts. And, they usually came with a "bonus" danger...the adhesive tape put on the sides to keep the stamps from sliding out. More often than not, the degrading tape gum would migrate onto the stamps making them absolutely uncollectible and utterly worthless.
I guess thats fair price Aravind, as long as you love the stamps. I recently paid $35 for a world wide lot. I really like the statehood page 2336-2348. I wonder if they have all 50 states? That would be a nice complete set.
