Pricing vintage photography lenses and cameras

My grandfather passed and left behind a box full of cameras and lenses. My grandmother asked that I see what they are worth and sell them for her. I have no idea where to start and was thinking about going to a local camera shop, but not sure they would be honest if there was something that was pretty valuable (and buy cheap to sell big).

I have listed here the items I have...

1. Vintage Kodak No. 2-C Folding Autographic Brownie
2. Minolta 110 Zoom SLR
3. Polaroid The Reporter
4. Kodak Signet 40
5. Auto Sears Macro 55mm 1:28 with 1:1 Adapter ring & Hoya UV(o) Filter
6. Vivitar 200mm 1:3.5 Auto Telephoto Lens
7. Auto Sears MC Zoom 70mm 1:28 Lens with Rolev MG Haze Filter
8. Yus Automatic 135mm 1:2.8
9. Auto Sears 135mm f:2.8 with Kamero UV Filter
10. Auto Sears MC Zoom 90-230mm 1:4.5 with Hoya UV(o) Filter

The Polaroid and the Signet would be really fun to use. Those are both sort of popular in hipster circles, but not really valuable.
