Nickels and Dimes

Hello,
A friend asked me to evaluate some coins from his dad. So I buy
a 2007 redbook and Making the Grade, a picture guide to grading coins.
These are coins from approx 1883 to present and most all are in albums.
Some of these coins, if they were in nice condition, would be of
considerable value. Examples: 1901S & 1913S quarters, 1895O & 1916D
dimes,
and 1885, 1886, 1912S, 1913S v2, 1918 D/17, & 1937D-3 leg nickels. With
some of these coins, especially the nickels, it's really hard to tell
what they are. I think the obverse would grade FR-2 and the reverse G-6
on some of the nickels...So, my question is, how does one determine the
value of a coin that grades less than a G-4? I do not see any certified
coins on ebay that are less than G-4... does that mean that the grading
services won't accept lesser grade coins for slabing? I think the
dimes and quarters would probably grade VG-8 and better. Next question:
Any thoughts as to how I should sell these? Time is not an issue and I
was thinking I might the lower dollar items as a year set under each
denomination. For example, sell the 1899, 1899O, & 1899S dimes as a 3
coin set. I don't think it would ne best to sell them in large groups,
like sell the entire 1913-1938 buffalo nickels in one listing... but
should I break it down so far as to sell each individual coin in it's
own listing? I can see listing the high dollar coins individually, I
don't know the best way to do the others.
I appreciate hearing anythoughts about this and if this post is in any
way inappropiate for this group, please forgive me. Thank you.
