Question on signed baseballs

[pt7464]

I'm not sure if this is the right place to ask this questions so if its the incorrect place please let me know.
I have a question on signed baseballs as far as value. I just purchased a very large collection of vintage cards and in the collection are a few signed baseballs. All the balls have the certificates of authenticity. The signed balls are Mantle, DiMaggio, Williams and a 1956 Yankee team ball. The signatures on the team ball are slightly faded but easy to read. Any help would be greatly appreciated.

You'll need to re-post this inquiry in the "Autographs" subgroup of the Memorabilia Section.

You will also need to post photos of the autographed Balls in question. Before anyone can assess the values, we would need to see the following...

A. Are they authentic, forgeries, or pre-printed souvenir Balls?
B. What company issued the COAs? (Many of these companies are worthless)
C. Condition of the autographs
D. Possibility of "clubhouse signatures" on the 1956 Yankees Team Ball

After seeing the photos, we can make a better determination of value.
