本物証明書(COA) – 本物のサイン入りサッカーシャツの保証書

At Iconic Shirts, authenticity and trust come first. The market for signed football shirts is growing rapidly, but unfortunately so is the risk of forgeries. To protect collectors and fans, every signed shirt we sell comes with a Certificate of Authenticity (COA). This certificate is your proof that the signature was genuinely placed by the player and that the shirt has been sourced through verified channels.

A COA is more than just a piece of paper. It often includes a hologram, QR code, or serial number that links directly to a database, and many certificates are supported by photographic or video evidence of the signing session. This makes a COA crucial not only for your peace of mind but also for preserving the long-term value and resale potential of your collectible.
