Hi Everyone !

My name is Rob and I found this site as I was looking for a place where I might find some objective analyses on a few items I have in my collection, first of which, I believe is a 1970 pirates team signed ball.

Ive grown increasingly weary of even the more highly regarded authentication comapanies such as PSA,JSA,BECKETT, etc but wanted to see if anyone could ID which Pirates Team signed ball this is (I suspect 1970 based on a few of the legible autos), and whether or not this would be worth the extra dollars to have it examined for authenticity  

As you might be able to see if i upload these pics correctly, all signatures appear to be done in pencil which makes it difficult to see great detail but any thoughts about the year and potential authenticity would be appreciated. The Clemente is faded but appears all there I think.

 I’ve bought most of the available literature regarding analysis of HOF’ers but am certainly a novice at best in understanding the nuances of each players hand. 

Is this worth the time and money to have it Authenticated? Are the super light pencil autos if authentic worth much in this condition ? 

Thanks ahead of time for any help anyone could be for me and thank you for making a forum like this with true collectors and enthusiasts.

Rob
