Grading math for this card
Prefilled with the latest qualifying sale for each grade where one exists. Replace any value with your own. We never suggest what grade your copy will get.
Formula from Grading: condition, uncertainty, and economics: grading pays only if your honest chance of the high grade exceeds (raw net + cost − other-outcome net) ÷ (high-grade net − other-outcome net). The 13% fee is an editable assumption, not a quoted tariff.
About Adam Bomb GPK
The 1985 Topps Garbage Pail Kids #8a Adam Bomb is a Series 1 sticker and one of the most searched GPK characters. Collectors search for it because the character, grade, back finish, and copyright variation can materially change the comp pool.
Why this card matters
Verified factPSA CardFacts identifies the item as 1985 Topps Garbage Pail Kids Stickers #8a Adam Bomb and records frequent PSA sales across grades. The opened source also links the character to the broader Series 1 sticker set, while outside the price table, the market separates Adam Bomb by grade and by back/copyright variation when that evidence is visible. CardVolume should therefore treat Adam Bomb as an exact sticker identity, not merely a character name. [1]
Identifying the exact version
AnalysisStart with 1985 Topps Garbage Pail Kids Stickers #8a Adam Bomb. Then inspect the back: matte versus glossy finish, checklist or license back, and one-star versus two-star copyright notation can matter. PSA's public CardFacts page records the core #8a identity but does not resolve every back sub-variant in the displayed sales table. When a listing provides only the front image, mark the back variation as unknown rather than assuming matte or glossy. [1]
What moves the price between versions and grades
AnalysisThe opened PSA table shows strong grade separation, with PSA 10, PSA 9, PSA 8, and mid-grade sales appearing in different ranges. Back finish and copyright variation can further separate copies when the source documents them. Condition matters because sticker edges, corners, centering, surface marks, stains, and print defects are visible and grade-sensitive. Use only sold comps for the same #8a version, grade, and known back type; exclude lots and unclear back variants. [1]
Authenticity checks
Verified factCompare against official references; multiple checks; no destructive tests; copied cert numbers exist. For Adam Bomb #8a, verify Series 1, Topps, sticker format, card number, name, back type, and copyright line. Inspect die-cut borders, edges, corners, surface, print quality, and back condition. For slabbed copies, compare the certification record with the holder and item photos. A valid cert lookup is useful, but PSA warns that copied cert numbers exist. [2]
Telling the versions apart
| Version | How to identify it |
|---|---|
| Matte back | Original Series 1 #8a Adam Bomb with matte back finish; verify back texture and exact checklist or license back. |
| Glossy back | Original Series 1 #8a Adam Bomb with glossy back finish; verify back texture and exact back design. |
| One-star/two-star copyright variations | Check the copyright line and star count on the back; record one-star and two-star versions separately when visible. |
