Tuesday Tips: What is a COA?

JSA. PSA. DNA. COA. If you’re just beginning to add to your personal collection, all of these abbreviations can seem confusing and overwhelming. Let’s take it from the top.

A certificate of authenticity is also known as a COA. This is the sole identifier that a piece of memorabilia is genuinely authentic. There are a hand full of reputable companies out there and we only work with the best. Every certificate of authenticity has a tamperproof sticker that is applied to the specific item and most come with a matching card to go along with each sticker serial number. The serial number then is entered into the third parties’ database (if applicable) so that the recipient of the memorabilia can easily verify the authenticity. This proof is what will keep the items value on the rise!

When you purchase an item with a COA, that means a third-party company is signing off that the autograph is authentic and real. In a world full of frauds and imposters, it’s imperative that you ensure any item you’re paying hard earned money for is the real deal. That’s why we only deal with reputable companies for COAs on our items.
