Oh boy, I just happened to get on and see this post first so I will give you my opinion. Psa and Jsa are the most legit of the big authentication companys,though they all do make mistakes. Ga in my opinion authenticates too many forgeries and carries 0 weight with me as far as authenticating autographs. My answer would be No they are not as reliable. And I know what others here will tell you.
GA belong with Morales and Max- total waste of space
While I am not a fan of PSA and JSA, GA is pure trash. At least w/ PSA and JSA, there's a general tendency to get it right. GA either does know, doesn't care or exists solely to empower the forgery business.
Just watch out for staff members 100,403 and 157,548. Those guys are just no good
Run from anything gai/ga as they are the forgers favorite authenticator since they love to pass forgeries.
GA is a complete joke, tons of Lebron/Manning/Luck/Jeter/Rivera/Puig forgeries. PSA/DNA and JSA make mistakes, but Global Authentics flat out stickers obvious forgeries over and over. Avoid.
Are you sure you just dont have slanted views Ryan?? Before placing blame, try and remember that its not Globals fault, its former staff members 5 through 257,387. GA is on ebays approved authenticator list, didnt you know. LOL
