Attic Find-grandpa's 12" Lenses

Hello all-

My mother recently gave me a box of assorted lenses which include a box labeled 12 3/16" x 2 1/8" pyrex optical flat, "VALUABLE", a 12" positive meniscus lens, and an 11"x3/16" (at the outer edge) positive meniscus mirror marked "px 1138" with initials O.C.L. There is also a plano-concave lens with a hole through the center. Other sizes and varieties too.

Though I have a fond memory of grandpa setting up one of his homemade telescopes in a dark meadow in upstate NY, observing the distinct rings and moons of Saturn, it's unlikely that I'm going to do anything with them in the near future. With two kids in college and every penney counting these days, I thought I might try to sell them if it's worth the effort.

Any help with what these may be worth would be deeply appreciated. Also if anyone knows of a bulletin board where I might post ads that would be awesome sauce.

Best, thanks in advance
