[CW] Value of Vibroplex Presentation & Vibrokeyer?

[Jeff T. Casey]

Hi gang,

I'm thinking of possibly trying to sell the two keys
described below, but I have no idea how much to ask
for them and I don't want to mess with auctioning
them, so I'm wondering if someone could please advise
me as to roughly what they might be worth.  Also, do
you have any idea how old they might be?

Vibroplex Presentation -- the nameplate on this key is
from the days when Vibroplex was located in New York. 
The serial number is 263594.  I bought this key used
in 1972.  It still works great, but needs a thorough
cleaning.  I believe the base (the top of which is
gold) is permanently somewhat discolored.  No parts
are missing, except for the tiny, decorative, red
plastic jewel that belongs at the top of the key.

Vibroplex Vibrokeyer single-lever paddle with tan base
-- the nameplate on this key is from the days when
Vibroplex was located in New York.  The serial number
is 260384.  I bought this key used in 1972 or 73.  It
is in good condition for its age and works great,
although it needs a thorough cleaning.  No parts are
missing, except for the tiny, decorative, red plastic
jewel that belongs at the top of the key.

Thanks very much in advance for any advice you can
offer.

73,
Jeff
