NeverOpened treats packaging as evidence. The goal is to preserve information before making an irreversible change.
Match exact identity
A nearby product name can hide a different printing, region, pack count, seal style or variant.
Match condition
A pristine case-fresh example and a crushed box can be the same SKU but not the same collectible proposition.
Use multiple sales
One outlier is a story. A cluster of comparable transactions is better evidence.
Account for venue
Auction premiums, shipping, taxes, platform fees and bundled lots can make headline prices non-comparable.
For high-value material, category-specific references and qualified specialists matter more than generic internet checklists.
