【奇跡の3連番】【PSA1】旧裏 ピカチュウpikachu Sequential 360 types in total] I

I am offering an extremely rare PSA 1 sequential set of three Japanese Pikachu promo cards.
This is a one-owner collection and all three slabs are in excellent condition.
Included Cards (Sequential Certification Numbers):
1997 P.M. Japanese Promo – Balloon Pikachu (Glossy CoroCoro Comics) – PSA 1
1997 P.M. Japanese Jungle Pikachu – PSA 1
2000 P.M. Japanese Neo Pikachu – PSA 1
These three cards are consecutively certified by PSA, forming a true sequential triple set.
Extremely Low PSA 1 Population Rates:
Balloon Pikachu: approx. 8% PSA 1 rate
Jungle Pikachu: approx. 0.6% PSA 1 rate
Neo Pikachu: approx. 0.7% PSA 1 rate
PSA 1 examples are already very scarce —
having three different Pikachu cards, all PSA 1, all sequentially graded, is exceptionally rare.
To my knowledge, this may be the only sequential PSA 1 Pikachu trio of this kind in the world.
