Frequently Asked Questions

The displayed buy prices for ★ StatTrak™ Butterfly Knife | Gamma Doppler Emerald (Factory New) exceed Steam's listing limit. SteamAnalyst tracks this variant across 16 marketplaces, including CSFloat, BUFF163, CS.Money. A missing Steam price does not mean the item is untracked.

Factory New (FN) ★ Butterfly Knife | Gamma 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 Gamma Doppler pattern hide wear better than others, making MW versions a strong value alternative.

The ★ Butterfly Knife | Gamma 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 Operation Riptide Case. The Gamma Doppler finish is particularly sought-after for its distinctive appearance, and supply is inherently limited while demand remains high from collectors and players.

Factory New covers float values from 0.00 to 0.07 on the CS2 wear scale. Within that band a lower float looks cleaner in game and usually sells for more, so two Factory New copies of the same skin can be priced well apart. Every listing's float is shown in the marketplace table above.

Right now the Factory New is quoted at about $7170.11 and the Minimal Wear at about $8622.49, so the Minimal Wear costs 20% 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 ★ StatTrak™ Butterfly Knife | Gamma Doppler (Factory New) Emerald vary across marketplaces due to fees, regional pricing, and seller competition. This skin can be obtained by opening the Operation Riptide Case or purchased directly from third-party marketplaces. The Steam Community Market charges 15% fees, while third-party markets like Skinport, DMarket, and Buff163 offer lower prices with 2-10% fees. 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. Key considerations: (1) Check the 30-day and 90-day price trends in the charts above; (2) Evaluate overall CS2 market conditions. Past performance doesn't guarantee future returns, but the ★ Butterfly Knife | Gamma Doppler has maintained steady trading interest. Diversifying across multiple items typically reduces risk.
