Most 1989 Fleer Baseball wax boxes being sold or broken at a premium are unconfirmed and should not automatically be advertised as containing the Billy Ripken FF or Randy Johnson Marlboro error cards.
A box can only be credibly tied to the true Billy Ripken FF if it came from a verified case with a code lower than 90171, ideally with BBCE verification. Lesser-known pre-black-box Ripken variations require a verified case code between 90171 and 90202.
For the true Randy Johnson Marlboro error, confirmed case codes fall between 83282 and 83362. Tint and partial blocked-out variations are only confirmed from case code 83482. Case codes 83552 and later contain corrected versions.
If the box is not BBCE verified, it should not carry a premium based on error-card speculation. Loose boxes shown next to a case prove nothing on their own, since empty cases have long been reused to market ordinary boxes as premium product.
Bottom line: unless the wax box can be tied to the proper verified case code, it should be valued closer to a standard 1989 Fleer box, not as a confirmed error-card box.
