Lots Of Old Coins Need Some Help

Ok, I'll try and make this short...or as short as I can. I had a volunteer where I work bring in coins that his grandfather had left him. He didn't know anything about them and turns out he wants to sell them. This guy is a real good guy and I want to try and find the best way to do this for him. What I'm asking for as a bit much in terms of help. I'm looking for help with grading and recommendations on whether they should be 'restored' and how I would get that done and if I should get them professionally graded. Who would pay the most for them(ie local dealers to avoid shipping, live auctions, ebay) and what your subjective values are. Yes, it's a lot to ask.

My other problem is I have a copier at work that scans them to pdf...which looks pretty good but I can't seem to convert them to show you. To give you an idea here's a brief list of the older coins.

1788 Carolous III 1R
2 x 1812 Half Pennies
1815-1830 Collonies of Commerce(not the one with the ship)
1820-bust and harp
1820-Upper Canada Half Penny Commercial Change
1837 Token - Province du bas Canada
1842-Province Of Canada
and on and on...most of these are in rough to really rough shape imo

I was some able to make shift part of the photo to give an idea of what these coins look like. Ignore my writing and values, I have no clue what I'm doing. I also don't know what errors to look out for if any...let me know if you want me to email anyone the pdf's. And thanks again for your time.
