Hello, I have noticed that sometimes when a card is up for auction the seller will state that the "book" value for the card is a certain amount

. Where would I go or where (besides The Yak Shack) (Not that I don't value the Yak Shack as a guide to the cards) would I look, to find out the "book" value of the Harry Potter Cards? Or is it the Appraisal value of the cards? I know that doesn't sound right. (I am not sure what the terminology is)

But if say I wanted to find the value of an antique toy (barbie or GI Joe.. for example) There are books that can give you that information. I figure there are probably books or a book that would give some idea of the value of the cards. I hope you can help me.
My HP cards have more sentimental value to me than any thing, but I suppose there is a monetary value as well, as I paid quite a bit for some of them!

(probably too much) but oh well! I was just wondering, I used to have a box of base ball cards and my grandma gave them away because she thought I had out grown them!

Well if any one wants to help me out I would appreciate it bunches!
PS I also need an avatar... I am completely computer illiterate, I read the suggestions, I just don't understand them. l

If any one would like to hellp me here as well, I would really appreciate it as well.
Thanks alot rosewhite
