Value of ivory keytops

[Jerry Hunt]

I have received a query by e-mail concerning the value of a set of ivory
keytops (excerpt below), and would appreciate any feedback regarding
possible current value. Thanks for any help you can provide.

   "Question - What is the value of a new old stock complete numbered
    set of Ivory Keytops. They were bought in 1980 and never
installed.         They are numbered so the grain matches."
