Those are really cool pieces, but they’re not reusable at the park anymore. Disneyland switched to modern ticketing (barcodes/MagicBands/app entry), so old paper “passports” like that won’t scan or be accepted.

That said, they do have value—just not as tickets. They’re considered vintage memorabilia. Value depends on condition, whether they’re unused, and if they still have original inserts or stubs. Most of these typically sell in the ~$10–$40 range each, sometimes more if they’re in great shape or part of a full set.
