1957 and 1966 Mickey Mantle (signed) -graded question

Good cards; read through that thread I posted and pay attention to which cards are worth grading and which are worth selling raw individually, and which to sell in lots.
My rule of thumb (with intent to sell) is to grade cards that will gain $20 by grading at the expected grade or lower, or ones that need to be authenticated to sell more easily. As in, any Mantle is probably worth getting graded just so you can sell it online without people thinking it's fake. Cards worth $20 or more are probably worth selling directly on eBay, while cards between $1-20 may be best sold on COMC where they do the work for you for a modest fee.
Cards that are worth less than a buck I normally donate to charity or sell in bulk. I just donated 2 tubs of cards to my church rummage sale.

Wow those Mantles are awesome! Check out the monthly specials section of PSAcard.com as they run quite often a flat 15 authentication fee on the nonpremium names. That is a good way to go but agree with others that you should probably focus on the bigger names.
