Condition Details
The card is currently housed in a top loader with a price sticker adhered to the plastic sleeve or surface. Visible centering appears slightly shifted to the left. Some minor surface wear and edge whitening may be present under the holder.
Grading Recommendation
Not recommended for grading. The cost of authentication and grading (approx. $15-$25) exceeds the raw market value of the card unless it is a guaranteed Gem Mint specimen, which is difficult with sensitive foil surfaces.
