Need your knowledge & expertise Ref. Collector Ed. Toolboxes

[CLugo]

I have 3 Snap On Tools boxes sitting in my garage. My ex left them behind many years ago and I am trying to figure out what they're worth so that I can try to sell them. My ex used to own a route and also worked for the company in sales for years. He won 2 of these boxes and I know they were scaled down two-piece versions of larger Snap On boxes. The third box is a small one piece box with a chrome handle on top. If you can lend me some knowledge on them, I'd appreciate it greatly! Here are some measurements (I have pics but cant get them to load):

Box 1: Two piece (Top & Bottom)
27" wide
14-1/2 " deep
Top piece: 13" Height
Bottom piece: 19" Height
Total height = 32"
