About Us

Agate Signed Sports is ran by passionate American sports fans and long term collectors of American sports memorabilia.


We pride ourselves on offering 100% professionally authenticated signed memorabilia across a range of American sports. All Autographs across the website are authenticated by market leading companies in the USA such as JSA, Beckett, PSADNA and Upper Deck to name a few.  

If there is something specific you're after that's not on our website, get in touch as we offer the option to source items for you. Having worked in America ourselves we have a variety of contacts that are able to source unique and rare items, so please don't hesitate to ask if there's something you are looking for.
