Every collectible at DMW is independently authenticated by a recognized third party — Fanatics, MLB Authentic, Beckett, JSA or PSA/DNA — before it is listed. You receive a serialized Certificate of Authenticity with your purchase, and most pieces carry a tamper-evident hologram you can verify directly on the authenticator's website.

Our guarantee is for life. If the authenticity of any item you purchase from DMW is ever credibly challenged, we will refund you in full — no time limit, no fine print.
