Baseball Card Exchange — the dominant authenticator of sealed trading card product in the hobby. BBCE-authenticated boxes and cases carry a sticker indicating the product was opened, inspected, verified for authenticity, and resealed (or kept in original sealed condition).

BBCE authentication is the de facto standard for high-value sealed Pokémon WOTC, pre-1990 sports wax, and similar sealed products. The premium for BBCE authentication is justified by the consistent counterfeit market in unopened product.
