Limited Edition IIgs - value?

[athene@smart.net]

A used computer shop that I work at recently obtained an Apple IIgs,
limited edition, signed by Wozniak on the front of the case.  

Could someone be so kind as to tell me if there is any extra value to
this beyond the $40 our pricing guide dictates for a 'standard' Apple
IIgs?  If there IS a market for this specific item, can anyone quote
me a ballpark figure?

Replies via e-mail would be appreciated...

Thanks in advance.
