Note: Steam Market shows the lowest current listing only. For knives with phase variants (Doppler, Gamma Doppler, Marble Fade) and items above Steam's listing cap, that lowest listing is often a chase-phase Emerald or stickered copy priced 5–10x above the typical-phase market. We display Skinport and Waxpeer instead — they reflect what the standard variants actually trade for.
