TRXDER / physical catalog
Collectible Registry
Look up a publicly catalogued physical copy using its unique Registry Reference (TRX-R) or a creator-assigned serial code. Registry references use unique database record IDs for faster lookup; creator serial codes are checked for conflicts but are not database-enforced unique. Neither proves physical authenticity or ownership. Older records without a normalized serial lookup key must be checked using their TRX-R reference until updated by the creator.
