#1 I wouldn't even want this ball because that signature will be completely faded away in 10 years
#2 It doesn't stand out as a 100% authentic, or 100% fake to me. Trout's signature is so simple there are sooo many forgeries of it. As I've said with Trout before, if you are wanting a Trout autograph, pay the extra bucks for MLB authenticated items, pack-issued cards, or know a very trustable IP grapher.
Thanks Ryan for the help! I'll pass on it then and get an MLB authenticated one. There was a game used one with MLB authentication that really caught my eye as well. Hefty price though.
