Authentication
Authentication & Grading
At The Finn Twinz, authenticity is our top priority. We understand that when it comes to sports cards, trust and verification are everything. That’s why every card in our collection undergoes a rigorous authentication and grading process to ensure you receive only genuine, high-quality collectibles.
Why Authenticate?
Authenticating sports cards protects you from counterfeits and reproductions, giving you confidence in your investment or collection. Our team works with industry-leading experts and trusted grading companies to verify the originality and condition of each card.
Grading Explained
The condition of a sports card significantly affects its value. Grading services, like PSA (Professional Sports Authenticator), Beckett Grading Services (BGS), and Certified Guaranty Company (CGC), evaluate cards on factors including centering, edges, corners, and surface quality. Cards receive a grade on a scale (usually 1 to 10), with higher grades indicating superior condition.

Mint or Gem Mint cards command the highest prices.

Cards with lower grades can still hold value but reflect wear or damage.
