La crosse 81

I bought this machine at an auction about 5-6 years ago for $150. It is missing the glass for the door and the key lock and it does get cold when plugged in. I didn't try to put money into it and it indicates 10 cents on the coin slot area and on the side.    The paint is faded and scratches in spots as indicated in the picture....any idea of value?  A co-worker is interested in buying it and I'm looking for a fair price.

Thanks,

Looks like a pretty neat machine to me! Parts he needs shouldn't be hard to find. If I owned it,I wouldn't accept less than $500.00
