Difference between clear and tinted windows?

Many months ago I took my 1964 Sport Fury to a mechanic and the driver's side window came out pretty scratched. I always thought the windows were clear and I've been looking on eBay for a replacement. I finally found one, but it is listed as "tinted." However, the eBay picture looks pretty clear. I checked the 1964 parts book and the factory did offer the windows in clear and tinted. I would not want to put in a tinted window if the others are clear.

How can you tell without having them side by side?
