Posted on 9/3/2025

Sell Like A Professional GmbH — Germany's leading sports and trading card marketplace — will help collectors in Germany and Austria access the full range of CGC's expert services for cards.

CGC® is excited to announce that Sell Like A Professional GmbH (S.L.A.P.) has been appointed as an Authorized Dealer in Germany. As an Authorized Dealer, S.L.A.P. will help collectors submit sports cards, TCGs and non-sports cards for expert authentication, grading and encapsulation services.

CGC is the hobby’s fastest-growing card grading company, with more than 8 million sports, TCG and non-sports cards certified since the service was established in July 2020. CGC uses expert graders, advanced technology and operational excellence to provide collectors with accurate, consistent, affordable and fast certification services.

S.L.A.P. was founded in February 2021 by Triantafillos Ktenidis & Christian Tietz who became frustrated as trading card sellers navigating inconsistent grading options and inefficient sales platforms in Germany. What began as a small project grew into a company trusted by thousands of European collectors, quickly becoming one of Europe’s leading submission and consignment services in the collectibles space.

Attending basically every card show in Germany and the vast majority of important trading nights in Germany and Austria, S.L.A.P. specializes in making the process of selling collectibles and grading cards effortless, transparent and professional. Being an Authorized Dealer now allows S.L.A.P. to offer fast, reliable and direct grading submissions to CGC from Europe, with the goal of making CGC’s world-class grading more accessible to European customers. That means submitters can expect quicker turnaround times, a smoother experience with customs and more trust in the grading journey. The community asked for CGC, and S.L.A.P. listened!

"Our partnership with CGC marks a huge milestone not just for us, but for the entire European trading card community," said Triantafillos Ktenidis, Director of S.L.A.P. "We're building the bridge that finally makes premium grading easy, fast and affordable across borders."

S.L.A.P. is now accepting submissions of sports cards, TCGs and non-sports cards on their website. Make sure to follow S.L.A.P.'s Instagram account to stay up to date on shows, auctions and much more. For additional information, email S.L.A.P. at [email protected].
