Which Eeveelutions lead the set?
Umbreon Prime #86 is the top grading target. ComicBook.com reported a PSA 10 sale at $90,000 alongside other elite Eeveelutions in the Eeveelution auction report. That result applies to true gem-mint copies with strong eye appeal.
Espeon Prime #81 matches that peak. ComicBook.com reported the same $90,000 PSA 10 result in the same auction event. Together, both Undaunted Eeveelutions reward gem-mint grading.
Why do LEGEND cards carry grade multipliers?
Kyogre and Groudon LEGEND #87-90 shows steep differences by grade. According to CardTrack, it is listed around PSA 10 $3,500, PSA 9 about $1,499, and PSA 7 $360, in the CardTrack price tracking. The drop below mint is sharp.
Scarcity also supports select LEGEND holos. PSA certification data places a 2010 Lugia LEGEND-Holo #113 at a $1,164 estimate with only 38 copies graded higher. Low higher-grade populations keep pressure on clean copies.
When does grading not pay?
Only truly mint copies pay off because values collapse below PSA 9 to PSA 10. A PSA 7 LEGEND can be worth a fraction of a PSA 10. Collectors chasing mid-grade copies face weak returns.
Houndoom Prime and Scizor Prime are weaker candidates. According to CardTrack, they lack consistent PSA 10 comps. Without repeat gem-mint sales, grading is a gamble.
How should you pre-screen before paying?
Check centering first, then corners, edges, and surface under bright light. LEGEND halves need extra care because two cards must both present well. A small flaw can remove the PSA 10 premium.
Compare your copy against PSA population data before paying grading fees. According to PreGradeCards, Umbreon Prime #86 has a thin PSA 10 population and a guide value near $4,560 in the 2026 Umbreon price guide. Submit only centered copies with sharp corners after checking population.
