I don't know if you mean confirm if the player on the Baseball is from the Houston Astros or confirm the authenticity of the signature so I will cover both.

Below I will leave a link to a Houston Astros Team Signed baseball price guide. Each year has links to full team rosters. Check (confirm) the name on the baseball to the roster

If you want to confirm/Authenticate the signatures.... Two of the top, and most trusted authenticators are PSA/DNA, and James Spence Authentic (JSA). Collectors will pay more for signatures authenticated by either one. It may sound odd but in some cases PSA/DNA, and JSA authenticated signatures may sell higher than a Letter of authenticity from an unknown or less trusted authenticator that witnessed the signing even though PSA/DNA, and JSA did not. It's just a matter of collectors trust, and collectors will pay more for it. Check the respective websites Show Schedule to see if they will be in the area that you live. They also do business through the mail. Before spending money on having the autograph authenticated do your homework. Find signatures on line that have been properly authenticated, and compare them to yours. If you feel comfortable that they are authentic then proceed. I will leave links to both the price guide and authenticators below. -Steven KeyMan
