All together, I would say $1000-1200 for a baseball signed by Boyer, Vuckovich, and Shannon.The ball looks like it's in great condition from the description. As long as you can still read the signatures, I would say it could go for $1200 max. and $1000 at minimum.

If you don't have a certificate of authenticity, then you NEED to get one or else the value of this ball will decrease. If you don't have a COA, you can get one from PSA/DNA or JSA.

It really depends on how many autographs those players signed. If someone signs a lot of autographs then the ball or picture is worth nothing. A Derek Jeter signed baseball is only worth a few hundred bucks.

I checked out JJ's links and I see how he got his numbers, but those seem awful high to me. These guys were all above-average players, but only Boyer would be remembered as a star. Maybe in the right market (St. Louis fans only) ,this ball could be worth a couple hundred. Personally, it would only be worth at most $50 to me.
