have a signed ball

[s10kool]

i have a ball signed by 1954 yankees w/ 27 names and i can find 20 on the 54 roster - has all the all stars and the managers name w/ mickey mantle etc.. i am leary of getting it out to get appraised because i have had it for years and it is kind of a nest egg. but i thought i would run it by some of your gear heads that might be into baseball collectibles. i want to know what it might be worth. thanks mike
