What can change Slippery the Seal's value
- Tag generation. Mint with both tags commands the premium, and an earlier swing-tag generation moves price more than condition does.
- Condition. Creases, stains, tag protectors and smoke exposure all show up in what buyers pay.
- Exact version. Pellet type, country of manufacture and renames make same-name toys different products at different prices.
- Listing quality. Most "error" listings describe common tag misprints that carry no premium; read titles skeptically.
About these prices
Values are based on completed eBay sales matched to this toy, not current asking prices.
How we calculate prices Hide calculation details
Included: Completed eBay sales matched to the toy and style number.
Excluded: Automated matching removes identifiable lots, cards, other Ty lines, reissues, and mismatched toys. Duplicate listings are collapsed. Some variation in condition or tag generation may remain.
How value is calculated: The headline value is the median sale price, weighted by units sold, with no outlier trimming. The observed range may include different conditions and tag generations.
