Crystal Pepsi Promotional Calculator

[chelz0r]

Hello,
New to the forum. My dad wants me to see if his crystal Pepsi calculator holds any value. I could not find any posted or old on Ebay. The only post that came up was one on WorthPoint, which I do not belong to, so I was unable to get a value from there. Has anyone seen one of these for sale before? http://www.worthpoint.com/worthopedia/1992-crystal-pepsi-promotional-solar-416412762

Thank you!
