This is a rare complete set of the clear acetate chase cards from Pokemon topps series 2 and 3. What makes this a perfect collectors item is that the cards have sequential serial numbers with their PSA grades.
Meaning they were graded 1 after another and all got a MINT 9 grade besides the Pikachu which got the NEAR MINT 8 grade. Pikachu PC1 - PSA 8 - Near Mint. Bulbasaur PC2 - PSA 9 - MINT. Charizard PC3 - PSA 9 - MINT. Squirtle PC4 - PSA 9 - MINT.
Mewtwo PC5 - PSA 9 - MINT. Venonat PC6 - PSA 9 - MINT. Mew PC7 - PSA 9 - MINT. Togepi PC8 - PSA 9 - MINT. Scyther PC9 - PSA 9 - MINT. Lapras PC10 - PSA 9 - MINT. The cards alone are rare, the complete set even rarer, graded NM-Mint even rarer, Sequentially graded serial numbers even rarer. This is something you won't see everyday.
