Our authenticity guarantee is straightforward: Every hand-signed item comes with an authenticity certificate. This certificate can be traced back to your purchase by using the serial number on it. Moreover, paper certificates accompanying your purchase add another layer of security. We only work with suppliers with perfect reputations, that’s why we vouch for every item we sell. Since entering the market back in 2007, we have built strong relationships with the most reputable collectibles companies in the industry.
