At Sports Integrity, authenticity is everything.

We guarantee that every item sold on our site is authentic and accurately represented, accompanied by trusted certificates of authenticity (COAs) and/or tamper-evident holograms from leading third-party authenticators including:

• Beckett Authentication Services (BAS)

• James Spence Authentication (JSA)

• PSA/DNA

• Fanatics Authentic

Many of our items come from private signings, reliable suppliers, or direct partnerships with athletes and celebrities. When available, we include supplemental documentation such as signing photos or event details to further verify the signature’s source.

Our commitment is to provide buyers with clear provenance, expert-backed verification, and the confidence to collect proudly.

Collect with confidence. Buy with integrity. That’s our promise.**
