Quick answer
Mil-Spec, Restricted, Classified and Covert describe ascending finish rarity in standard cases.
Container and collection records should be read as structured relationships. This prevents a visual similarity, old forum post or copied market listing from becoming an unsupported drop-pool claim. Read the color hierarchy used inside weapon cases and simulators.
Mil-Spec, Restricted, Classified and Covert describe ascending finish rarity in standard cases.
A rare special-item result is modeled separately from the four weapon-skin tiers.
Rarity is not a price guarantee; demand, wear, pattern and supply also matter.
Published odds should be identified by source and never silently adjusted.
How to read the data
Begin with the exact record involved: item name, variant, source and observation date. Then separate a factual game-data field from an estimate, community convention or market inference. This sequence keeps a helpful shorthand from becoming a false claim.

Common mistakes
Treat a listing as a sale
Asking prices can be stale, manipulated or far from executable demand.
Hide model assumptions
Fees, odds and freshness windows must stay visible and editable.
Match the exact variant
Wear, pattern, StatTrak, Souvenir and event identity can change the record.
Keep an unavailable state
Missing evidence should remain missing instead of becoming fabricated data.
