New collector need help with 1910 and 1911 cards

[ptowncoug3012]

My grandfather just opened his safe deposit box after 40 years and gave me his card collection that he received from his uncle 40 years ago.
From my review of the collection I have the following
47 cards plus some dupes from 1910 Obake 150 and 175 subjects
19 cards from 1909 Obak Old English series
173 plus dupes from the 1911 Obak Red Back series
10 cards from the 1911 Turkey Red
85 cards from 1911 Zeenut
10 cards from 1912 Mono (T217)
10 cards from 1910 sporting life.
Included in these cards is the Weaver 1911 Zeenut that I just sold at auction for $17k in Oct. 2009.
None of these cards he gave me have ever been graded, but from what I can tell are near mint to mint as they have been kept in safety deposit boxes b/t my grandfather and his uncle for nearly 10 decades.
I have no clue where to begin or who to turn to have these graded, or even if I should. He gave them to me with the intention that I sell them, but I am not sure. Just a bit overwhelmed as really didn't realize the value, just thought it was great that these were 100 years old!
I would be much appreciated on some guidance. I have compling an inventory on excel of the cards and I also plan to scan them.
