Driving myself nuts trying to learn how to authenticate signed baseballs. Got into the hobby almost by accident - couple members of my family & I helping a friend in need of cash by buying his collection (or maybe consider it a collateralized loan since I think he wants to buy them back when times get better).  Love the balls and find myself obsessed with learning more.  My concern is that many did not have COA's or had questionable COA's. I'm not in a position right now to put more money out authenticating them (nor do we have any plans to sell them). They were all purchased on eBay between 2006 & '07.

Nervous about posting them because I don't want to find out any are forgeries but I have been too preoccupied with my new obsession (& work is suffering). 

So starting with Mickey, Joe & Ted (one of them has a PSA/DNA cert)...

Thanks in advance for your help - I have more to post if that's ok.
