Description
This is a 1997 Japanese Pokémon Fossil Expansion card titled 'Mysterious Fossil' (なにかの化石). Notably, this is an early print error card featuring 'HP10' instead of the intended 'HP40' or 'HP' text standard. It features artwork by Keiji Kinebuchi and the original Fossil set symbol (skeletal hand) in the bottom right corner. The text is entirely in Japanese.
Key Features
Vintage 1990s Pokemon card; Japanese Import; Notable HP 10 error print which was corrected in later print runs; classic Fossil set iconography; Illustrator Keiji Kinebuchi.
Authenticity Indicators
Correct color saturation; sharp printing of the Fossil expansion footprint logo; correct font for 'TRAINER' and Japanese characters; Illus. credit matches official data. Confidence: High.
Flaws to Note
Softening/wear on all four corners; silvering/whitening along the top right edge; minor surface scuffs. These flaws significantly prevent it from being a high-grade professional submission.
Selling Guide
Where to Sell
eBay or TCGPlayer are the best venues for specific Pokemon variants. Facebook Pokemon Buy/Sell/Trade groups are also effective for low-value vintage.
Selling Tips
Use keywords like '1997 Pokemon Japanese Fossil', 'Mysterious Fossil HP 10', and 'Vintage Error Card'. Provide clear photos of the back corners as that is what collectors use to judge condition. Ship in a penny sleeve and top-loader (semi-rigid mailer) to prevent bending.
