Was pretty skeptical about a purchased of a signed item I was planning on getting. Sent an email regarding the process of how to get it through on a Saturday morning (they are closed on weekends) I immediately got an email back from Mr Steve. The owner! He walked me through it and got the process in order! The signature turned out to be legit! I waited until Monday and called Mr. Steve and he instantly made an appointment to meet me that day to do a Letter of Authenticity!!! I drove an hour to see him and he told me it would take about 2 hours! I sat in my truck and he called me in about 50 mins to tell me it is all done! Cant wait to bring note signed items in! Thanks Steve! read more

I needed some guidance with some old baseball cards as I had no idea where to start. Steve was exremely helpful on educating me with my options. He definitely knows his stuff. He sorted out the cards that warranted attention from those that aren't worth my time. The task of selling my cards isn't as daunting now thanks to Steve. read more

Steve Sipe handled my authentication request with the utmost professionalism. He has great knowledge as well as having great connections with professional athletes. The process was fast and simple. Thanks again Steve. read more

Fantastic!! love Global 5 stars A+++ I have been doing business with Global for many years and I always get 5 star service every time. Thank you read more

The company is under new ownership. I couldn't be more happy or more satisfied with my personal dealings with Steve Sipe, the owner and lead autograph authenticator at Global Authentics. He's a true professional. He was ALWAYS honest and upfront with me. His communications, be it a phone text or an email, was always sent to me in a timely manner. He's extremely knowledgeable about autographs. The message that I'd like to convey to some of these other autograph authenticators: You can learn a thing (or five) from Steve Sipe, as it relates to how to interact with clients in a professional manner. Also, not authenticating a GENUINE autograph is worse than authenticating a forgery! Thanks again, Steve at Global Authentics. read more

Global should be the most popular company in my opinion, The others have gone mad with power and greed, You dont get the personal time and attention as you get at Global, Steve Sipe is the lead expert and he takes this very seriously. He will try his best to get you a real opinion and he will study your autographs carefully, Unlike other unknown experts you can contact this team personally, They will give you the best opinion that they can, If they aren't certain and cant provide you with a thoughtful opinion you will get a refund if inconclusive, You will get a very nice price regarding their fees. And you get a quality COA letter and a registered sticker and a nice looking card coa, Also i have spoke with Steve many times and he is truly a expert in my opinion as a collector, He knew things that all the other companies didn't know, I wont give them any free advise, But trust me steve knew that facts about certain fake books I've seen posted many times, The other big companies dont know about these books and they authenticate them. Never think the other companies know more. They dont, I see there authenticated fakes on ebay everyday and it sickens me , I trust global to study my autograph as if their reputation is at stake and that is great thing , They dont just take your money and authentic junk, Steve is very friendly and a super great guy, I will always choose his opinion over all others besides my own. I didnt write all of this for no reason, I feel they deserve respect and your business, And yes he has failed a couple of my autographs but he was right and i got a refund from the seller, Ebay will accept his opinion in a refund case, Thanks Steve and your team read more

I spoke with Steve the owner for thirty minutes about a piece he and his team certified and I got to say this is the real deal! His knowledge and experience is truly amazing. I can't wait to get my piece and I will be sending all my autos here from now on! read more

I went down to Global Authentics in Carlsbad, and found establishment impressive and very informative. I will review with Steve Sipe or his staffs before I make my future purchases . He gets back with you right away and let you know his professional opinion that I value. I appreciate his honesty whether it's good or bad. I have been collecting sports memorabilia as a hobby and have been collecting for over 20 years and Steve has been great in reviewing my collections. I highly recommend his digital online review before purchasing any sports memorabilia. I was at a sports show few weeks ago n was able to send photos of autographs on a Saturday, and Steve got back with me immediately with his opinion on vintage sports autographs which saves me hundreds of $$$. Thanks Steve read more

If you are looking for a place to get your autographs authenticated this is the place. This can be a very expensive ans stressful hobby. Working with Steve made everything so much better and less stressful. His knowledge is like no other. He genuinely cares and loves what he does and is all about his customer. With there being so many choices in this hobby, I wouldnt even think of going anywhere else. read more

I had some items that had been certified by GA 7-8 years ago and Steve helped me out to get them re-certified and upgrade me to LOAs. He bent over backwards to make sure I was happy and taken care of in some transactions with the jerseys and speaking directly with the buyers and always being available to answer calls/texts at all times. A+++++ service and I would recommend GA to anyone!!!!! read more

Wow. I am very impressed by their skill and service. I was looking for a local place to authenticate an autographed Tshirt (by Mostly child TV actors from 1994) and I was able to bring it the next day. The best part is - there were 2 signatures on it that I could not figure out, but Steve figured them out! Upon checking online he is correct. Amazing. Highly recommend. read more

We were looking to authenticate a few baseballs we had in the family for a fundraiser after our son was diagnosed with leukemia. Steve was amazing to work with! He authenticated 3 of our four baseballs. Fingers crossed they are popular for the silent auction! Thanks Steve, for your care, compassion and professionalism. read more

Turn around time is quick, customer relations are kind and very easy to reach out to!! Thank you for your work!! Global Authentic is not the old GIA , he has invested in making his services The best and integral and done accurately and precisely!! Thank will continue to use your services!! read more

This service has been known to provide an enormous amount of fake signatures. They is will verify just about anything that seems passable. I've personally been burned by them before, and refuse to ever use the service again. As a collector, you'll do much better going through one of the more well known authenticators, not risking your money on something that is far more likely to be worthless than real. From what I've seen, you're better off having something with no COA than one from Global. I wouldn't trust any of the other reviews here, they are clearly amateur or have other intentions. SAVE YOURSELF FROM A BAD EXPERIENCE. read more

When the owner answers the phone that's a great first start! Steve spent almost an hour answering all my questions and I feel very comfortable sending my items. Do I like I did try Steve and his crew and form your own opinion like I did Steve is a great guy! Thank you sir for your time and the education 5 stars just doesn't seem enough ! You are a class act! read more

Global Authentications is awesome and so is the CEO Steve Sipes. They are accommodating and they know what's the "real deal" and a what's a fake (knock off). I'd use GA over JSA or PSA any time. Thanks. read more
