Do you need your sporting memorabilia authenticated? 

Worldwide Signings have over 30 years experience in the business. We can supply you with your Certificate of Authenticity. Every item is checked thoroughly, we will never pass an item that we are not 100% convinced is authentic just to make a quick sale.

We only use industry experts and one of the most respected men in the business and friend of the Ali family, Tyrone Monaghan is our expert analyser for all Muhammad Ali memorabilia.

After passing inspection you will be supplied with your Certificate of Authenticity which will have a unique embossed Worldwide Signings stamp (to prevent forgeries), the COA will also include an image and as much information on the item as is possible, a unique serial number which is logged in our database. The COA also includes my full name, address, email and website.

The following autographs are accepted but be advised that they are scarce autographs with less extensive exemplars available and may require longer time in-house to inspect. In some circumstances, there will be a greater chance that the autograph will be returned as 'Inconclusive/unable to render an opinion'. The policy is the same as it is for all autographs. The autograph will either pass and receive a COA, or it will not pass our authentication. We set a high bar for these autographs as we do for all our autographs we authenticate. We don't 'guess' and we will return it as 'Inconclusive/unable to render an opinion' if we are not positive one way or another. Our clients respect honesty and we don't keep a fee just to keep it nor do we pass something 'on the fence' just to pass it.

Shipping costs both ways are non-refundable but if the submission is sent along with other autographs it will of course piggyback on the return of those autographs and will be less of a financial burden for you. If you have any questions, contact us and we can explain everything in more detail for you. 

All Managers/ trainers/ boxing promoters/ ring officials/ referees/ announces/ historians autographs are £15 each. This includes but is not limited to Martin Julian, Tex Rickard, Jack Kearns, Jack Blackburn, John Roxborough, Julian Black, Jim Norris, Marshall Miles, Al Weil, Charley Goldman, Bundini Brown, Wali Muhammad, Ray Arcel, Angelo Dundee, Don King, Freddie Roach, Lou Duva, Bob Arum, Michael Buffer, Arthur Mercante Sr., Mills Lane, Richard Steele, Hank Kaplan, etc. 

Be advised that just like the Old Timer / Legends submissions, these autographs may encounter a higher rate of 'Inconclusive/unable to authenticate' decisions and a voucher for the submission fee may be issued if we cannot determine its authenticity unless you request a 100% full cash/cheque/money order refund of the submission fee. Shipping costs both ways are not refundable. If you submit the autograph with other autographs, it can piggyback those autographs to save you on the return shipping charge. As always, if you have any questions, please contact us.

Women Boxers

All women boxers £20 each for Flat or non flat.

​Boxers whose careers started pre-1930, please contact us.

All male boxers not listed are a flat fee of £10. This includes champions / challengers or any boxer that was of note during his career. If you are not sure if we authenticate your name, please contact us. All boxers with careers that started Pre-1930's, please contact us as we reserve the right to adjust the fee for any of those names.

Shipping costs both ways are not refundable if we give an 'Inconclusive/unable to render an opinion' decision. If you submit the autograph with other autographs, it can piggyback those autographs to save you on the return shipping charge. Contact us with any questions.

We reserve the right to correct any boxer listing and price due to oversight/technical/typographical errors on our part. All prices will be honoured for boxers we list in the premium value/ vintage/ rare autograph section otherwise.
