COLLECTOR'S BREAKDOWN: BROCK'S MANKEY - GLOSSY COROCORO COMICS (PROMO) [#56]
This is a vintage Japanese Pokémon card featuring Brock's Mankey, originally released as a 'Glossy' promotional insert in CoroCoro Comics. The artwork by Ken Sugimori depicts the Pig Monkey Pokémon in a dynamic, aggressive pose against a forest backdrop. Notably, the card features the old-school 'Pocket Monsters' Japanese card back and includes the Gym Leader Brock's portrait in the lower right, signifying its association with the Gym Leaders of Kanto.
CULTURAL CARD LORE
Where This Object Echoes
Mankey's design and temperament are inspired by the Japanese Macaque and the concept of 'unbridled rage' found in various simian spirits in folklore.
Ritual & Ceremonial Use
- •Magazine-based distribution which was a central social ritual for Japanese youth in the late 90s to acquire exclusive collectibles.
Meaning Through Time
A playable competitive piece representating a specific Gym Leader's team.
A nostalgic artifact representing the 'Golden Age' of Pokémon's early Japanese history.
CARD HISTORY & PRINT RUNS
COLLECTOR INTEL
CoroCoro promos like this one were the only way to get certain 'Glossy' variants, which have a distinct, highly reflective surface compared to standard matte cards.
This Mankey card features the 'No. 056' Pokédex number, which corresponds to its position in the original 151 Pokémon lineup.
HOW SCARCE IS IT?
Genuinely harder to find. Perhaps only dozens come to market annually. Collectors actively watch for these pieces.
Typical Characteristics
- Dozens per year at market
- Documented provenance valued
- Active collector pursuit
Confidence Factors
- Housed in a legitimate PSA slab with a verified certification number (43638462)
- Correct 'Glossy' surface texture and vintage 'Pocket Monsters' back design
- Label typography and holographic security features on the slab appear authentic
GRADING EXPERT'S TAKE
Trading Card Market Analyst
High confidence due to the presence of a professional PSA grading slab, which provides independent verification of authenticity, set identification, and condition grade.
KEY EVIDENCE
- 1PSA Cert #43638462 identifies it correctly as the 1998 Glossy CoroCoro promo.
- 2The 'Glossy' sheen is visible in the light reflections on the card surface.
- 3Japanese 'Old Back' design (1996-2001) is present on the reverse.
- 4Lower right Gym Leader symbol (Brock) is present.
WHAT WOULD IMPROVE CERTAINTY
- →Verify the PSA certification number on the PSA official website database to confirm the registry entry.
- →Condition of the acrylic slab should be checked for scratches; a sleeve can prevent further wear to the case.
CONDITION & GRADE
Grading breakdown
The PSA label confirms a Near Mint 7 grade. Centering on the front appears slightly off-ratio (approx 60/40), which is common for this era. Minor edge wear on the reverse likely prevented a higher grade.
Condition
Professionally graded PSA 7 (Near Mint). Visible centering is slightly heavy toward the left on the front. The vintage Japanese card back shows clean edges with minimal whitening.
Surface
Card features the characteristic 'Glossy' coating exclusive to early Japanese CoroCoro promos, providing a smooth, high-sheen finish that is more reflective than standard cards.
Weight & feel
Lightweight cardstock, protected by a sonic-welded plastic PSA slab, providing a rigid and substantial feel compared to a raw card.
