Thanks for the info. That is kind of what I have been using it for so far, as well as just a google search for key and semi-key dates. There are a half dozen or so that have peaked my interest simply because of age and condition, but nothing I found suggests anything there is a key or semi-key.
So it sounds like the Red Book won't help me too much... is there a good resource to figure out some average prices? Like I said, most of what is in the collection is average, circulated condition. I'm trying to give my mom 3 values for the collection - face value, melt value, and numismatic value. I'm good figuring out the first two, but the third I'm struggling with. Along those lines, is there something similar to a redbook for paper currency? you can see what he had in my original thread, but that is stuff I have NO idea on value.
I'm basically doing a pseudo-appraisal for my mom... she has zero knowledge of coins (so only slightly less than me

) and just wants an idea of what it is worth. Long story short, the collection was split in to thirds when Grandpa died (one for each of the children). I have no idea what happened to the other 2/3 of it, but mom has decided she might try and sell her 1/3 since I am here only child with an interest. Plus she knows her dad wouldn't want us holding on to it just because it was his, he would rather my mom sell it and use the money for something for the family. I may try and buy some of the collection, but most of what I'm interested in would be buffalo nickels and silver at the moment.
