Complete NG collection for sale.

I just inherited a complete collection, from the first edition, to the last. I believe that they are all there, but I have not taken an inventory. The early years are bound, some reproductions, some original, but bound. Just the first 20 or so years are bound, the rest are singly edition originals. 

I have no idea of the value, and I dont want to sell individual copies, as my brother -in -law went to a long process to acquire all of the missing editions.

I have a video of the set, but it is too large to upload. will update this post when I can manage it.

Any ideas/ serious inquiries only, please.
