Japanese-language trading card consistent with Pokémon Gym series

This is a collectible trading card featuring Japanese text and artwork consistent with the Pokémon Trading Card Game. The card depicts a Geodude illustration, attributed as printed to 'Illus. Ken Sugimori' in the bottom left corner. The top text reads 'タケシのイシツブテ' (Takeshi's Geodude), noting a 'LV.13' and 'HP40'. The card features a Fighting-type symbol in the top right and art of a character consistent with 'Brock' (Takeshi) alongside a gym badge symbol in the bottom right frame. It appears to be made of standard cardstock with a yellow border and a tan/brown textured background in the text area. The card shows signs of minor edge wear and slight surface scuffing characteristic of handled collectibles. While the layouts and markings are consistent with the 'Gym Heroes' or 'Gym Challenge' expansion sets from the late 1990s, this item is unauthenticated. Physical inspection by a professional third-party grading service would be required to verify printing origin, age, and legitimacy, as high-quality replicas of such cards are common.

I have examined the images of this trading card, which bears markings and artwork consistent with the Japanese 'Gym' series expansion, specifically 'Takeshi’s Geodude' (タケシのイシツブテ). Based on what I can see, the layout, HP, and 'LV.13' designation match the typical printing patterns for this era. However, I cannot verify the physical age or printing origin from a photograph alone. The minor edge wear and surface scuffs suggest handling, but I would need a physical inspection to confirm the cardstock's core and surface gloss. This value estimate is based on the assumption that the card is a period-accurate Japanese-market printing; if it were determined to be a high-quality replica or modern copy, the value would be negligible, likely under $1.00. Generally, the market for vintage Japanese gym-set common cards remains stable among niche collectors, but professional third-party grading would be necessary to establish a higher premium. To confirm its status, an in-person examination of the halftone printing patterns and light-transparency of the cardstock is required. Without such verification, the item is valued as a raw, unverified collectible consistent with secondary market trends for this specific Pokémon character.
