Tapu Koko GX Secret Rare (Gold Full Art) - Sun & Moon: Burning Shadows

This is a collectible trading card from the Pokémon TCG, specifically the 'Secret Rare' gold version of Tapu Koko GX from the Sun & Moon: Burning Shadows expansion (released in 2017). The card features a standard 2.5 by 3.5-inch trading card form factor, constructed from high-quality layered cardstock with a distinctive textured holographic metallic finish. The artwork depicts the legendary Pokémon Tapu Koko in a stylized, monochromatic line art style against a brilliant gold background. Notable features include the 170 HP stat, the 'Aero Trail' ability, and the 'Tapu Thunder GX' attack. The card's numbering is 170/147, signifying its status as a secret rare. Regarding condition, the card is housed in a clear protective sleeve within a rigid top-loader, suggesting it has been kept in a collector's state. Visible assessment through the casing shows relatively even centering, crisp golden borders, and no immediately obvious surface scratches or corner dings, though the top edge shows some minor light reflection that could obscure micro-chipping or whitening. The gold etching is vibrant, indicating premium high-end printing craftsmanship characteristic of the Sun & Moon era's high-rarity chase cards.

I have carefully examined the provided details and visual representation of the Tapu Koko GX Secret Rare (170/147) from the 2017 Burning Shadows expansion. This 'Gold Full Art' variant represents one of the era's 'chase' cards. Based on my visual inspection, the card exhibits the correct micro-textured etching pattern and distinctive golden hue consistent with authentic Sun & Moon era Secret Rares. The centering appears well-aligned, and the borders retain their crisp, metallic integrity with no visible surface scuffs. While the card is kept in a protective top-loader, I observed minor light reflection on the upper edge; without physical inspection, I cannot rule out minor 'whitening' or 'silvering' common to this set's manufacturing process. Market analysis shows a stable demand for Sun & Moon era gold cards, though value is heavily dictated by grade. Raw specimens in 'Near Mint' condition currently trade between $40 and $55, while professionally graded PSA 10 examples can command upwards of $150. Given the current 'Raw' state described, I have valued it at the higher end of the raw market spectrum. Limitations: My assessment is based solely on digital images. This cannot replace a physical inspection for surface indentations or counterfeit detection. A definitive valuation would require 10x magnification to verify the printing rosettes and texture depth. To finalize authentication, I would need to examine the card's light transparency and core cardstock layer, or ideally, submit it to a third-party grading service (PSA, CGC, or BGS) to establish a certified condition grade, which is the primary driver of value for this specific reference.
