Frequently Asked Questions
The displayed buy prices for ★ M9 Bayonet | Doppler Sapphire (Minimal Wear) exceed Steam's listing limit. SteamAnalyst tracks this variant across 16 marketplaces, including CSFloat, BUFF163, TradeIt. A missing Steam price does not mean the item is untracked.
Factory New (FN) ★ M9 Bayonet | Doppler skins have float values between 0.00-0.07, showing minimal to no visible wear. Minimal Wear (MW) floats range from 0.07-0.15, with slight scratches or fading. This skin has a restricted float range (0.00-0.08), meaning Battle-Scarred versions don't exist. The price gap between FN and MW varies by finish — some designs like the Doppler pattern hide wear better than others, making MW versions a strong value alternative.
The ★ M9 Bayonet | Doppler commands premium prices due to several factors: First, knife skins are the rarest drop category in CS2, with approximately 0.26% chance from case openings. Its Covert rarity means only about 0.64% of case openings yield this tier. It can be unboxed from the Chroma Case. The Doppler finish is particularly sought-after for its distinctive appearance, and supply is inherently limited while demand remains high from collectors and players.
Minimal Wear covers float values from 0.07 to 0.15 on the CS2 wear scale. This skin's own floats run 0.00-0.08, so its Minimal Wear copies sit between 0.07 and 0.08. Within that band a lower float looks cleaner in game and usually sells for more, so two Minimal Wear copies of the same skin can be priced well apart. Every listing's float is shown in the marketplace table above.
Right now the Minimal Wear is quoted at about $3935.65 and the Factory New at about $926.78, so the Minimal Wear costs 325% more. How much of that gap is worth paying depends on the finish: wear shows first on edges and raised areas, so on some designs the cleaner wear is hard to tell apart in game. Switch wears above to compare the two side by side.
Prices for the ★ M9 Bayonet | Doppler (Minimal Wear) Sapphire vary across marketplaces due to fees, regional pricing, and seller competition. This skin can be obtained by opening the Chroma Case or purchased directly from third-party marketplaces.

Compare real-time prices in the market comparison table above to find the best deal.
Investment potential depends on several factors. Knives and gloves historically hold value well due to consistent demand and limited supply. Covert rarity items tend to appreciate over time as cases are opened and supply gradually decreases.

Past performance doesn't guarantee future returns, but the ★ M9 Bayonet | Doppler has maintained steady trading interest. Diversifying across multiple items typically reduces risk.
