Sim City for DOS

I recently acquired a copy of SimCity for Dos from 1989/1990 era of PC gaming and wondering if anyone knew the price of how much I can sell it for on ebay? It is still in it's shrink wrap so, it has never been used. Just wanted to know if anyone has come across this I have searched ebay and google and come with nothing  on this. 

I wouldn't expect much, $30-$60 if you're lucky. I saw a sealed copy go on eBay for $200 for over a month, never sold at that price.

Okay I see that older PC game it is that the less the value of it is because of relevance as to actually using rather then collecting it .
