I have several autographed baseballs...
Bob Gibson and many others from decades ago.

Now I know my mother bought them from Stix, Baer & Fuller (now defunct store) many decades ago. Each of them comes in a case and a box that says on the outside that it is an authentic autographed baseball. Now there's no certificate of authenticity or anything, so how does mine compare to others out there and may I assume they ARE authentic???

Thanks.
