I've not seen the actual keyboards in person, but the auction mentions
these keyboards were made by Roland, for use in Rodgers organs. The site
also has a few pictures which can be enlarged a fair amount.

Having repaired Rodgers organs for several years, I can tell you that these
keyboards do indeed use the conductive rubber contacts. This is the style
of contact used on the smaller Rodgers organ consoles. Some of the larger
consoles still use metal contacts, but I can tell from the pictures of the
keyboard's bottom side, that these are the conductive rubber contact style. 

Had they been metal contacts, you would have seen the actual gold-plated
contact wires in the following photo:
