Authentication Services

Let Green Jacket Auctions authenticate your golf autographs & memorabilia!

Why Authenticate with Green Jacket Auctions?

In this day and age, authentication and provenance are key aspects of collecting antiques and memorabilia. Simply put, authentication from reputable sources dramatically increases both the value and investment potential of your golf memorabilia.

At its core, Authentication is a way to have recognized experts give their professional opinion of whether something is real or fake. But Authentication has evolved into so much more. It has now become a way to further document and catalog golf memorabilia. In fact, with many of the items currently being authenticated by Green Jacket Auctions, the owner does not even question the item’s authenticity.

Oftentimes they are autographs or memorabilia obtained personally by the owner, but Authentication is sought to further bolster the item’s value and provenance. Amazingly, a majority of the memorabilia authenticated by Green Jacket Auctions are from collectors that have no intention of selling the item in the near future. But Authentication from Green Jacket Auctions provides comfort to the collector – both in terms of authenticity and value.
