Baseball Cards Price

Where do I grade baseball cards/comics?

I have plenty of stuff to sell,signed records,signed books,signed baseball cards,and just signed meorabilia.The problem is that I need to know where you grade/authenticate those? I have noticed that when you try to sell something if it's backed up by a document the value increases,where do I go?

2. For the baseball cards go to ur local hobby shop or sports collectors store also there are magazines that can u give a general idea what ur baseball cards are worth. For ur other things go to an appraiser who specializes in signed memorabilia. Also get a certificate of authenticity with ur signred items.
