[meteorite-list] How Do I Determine the Value of My 50 Milimeter Sphere Collection

[bobadebt at ec.rr.com]

I am at a point in my life where priorities have change and I wonder what I 
will do with the things I have collected over the years.

My 50 millimeter sphere collection  has a special place in my heart but I 
don't have the resources to grow my collection so I know at some point I may 
want to sell it.

But other then eBay I have no idea of where I could sell it nor do I have 
any way to to determine the value since it is a very unique collection.

Here is a list of my collection, all of the spheres are 50mm in diameter.
