Is my South Park Slot Machine glass worth anything?

I have the belly glass from a South Park slot machine prototype that I
was told was 1 of 10 in existence. I have searched extensively for
this online, and cannot find any information on what it might be
worth. The glass piece has all the characters from season 1 on it, and
at the bottom it has the comedy central stamp along with the year
1999. I know its completely genuine because somebody I know got it
from somebody who worked at IGT when they made the prototype. The
reason they never made a SP slot machine was because the Nevada Gaming
Commision thought it would lure in underage gamblers. Anyways, I am
super broke and have been told by a few people that it could be worth
some major dough.
