In CS2 you will find quite a few skins whose appearance is affected not only by float, but also by pattern-index. Most often these are colorings with geometric and abstract patterns, which depending on the pattern-index can be applied differently to the surface of the weapon. Usually these versions cost the same, but in some cases certain pattern-index values yield unusual or something noteworthy variants. Here are a few skins for CS2 that have a successful pattern-index that can increase the price noticeably.
AK-47 Case Hardened (Surface Hardened)
AK-47 Case Hardened is covered with a pattern of irregularly shaped spots that mimic the texture of hardened metal. Combining multiple colors provides many opportunities for variants to appear that will have a pattern-index that will radically affect value. The most valuable are the variants with the maximum presence of blue color, especially if it covers the entire top. Gold versions of the skin are also of interest to collectors, but they are more common, as there is less blue coloring.
Glock-18 Fade (Gradient)
.
Another category, as famous as Case Hardened, is skins with Fade pattern. As an example, let's mention Glock-18 Fade. Variants with a predominantly purple coloring and little or no white at the end of the barrel can cost several times the price of regular – and this skin is already quite expensive.
XM1014Seasons (Seasons)
However, there are many more skins for which the pattern-index matters. For example, this shotgun skin is covered with a pattern that resembles fall leaves. But among the many red, yellow and green leaves, there's a blue one hiding. XM104 Seasons variants that show this blue leaf will cost more. These will be the versions of the skin with indexes #26, #78 and others.
AWP PAW (Paws)
This sniper rifle skin is covered with bright cartoon images of dogs and cats. Which ones turn out to be visible depends on the pattern index. The most valuable are the variants that show a golden kitty – the Chinese symbol of good luck. These include, for example, AWP PAW with index #19 and #35.
Glock-18 Moonrise (Moonlit Night)
.
Another popular skin in this category is – Glock-18 Moonrise. The top of the gun shows a purple and black cityscape, but some variants have an interesting feature: the star image appears just near the trigger. Such copies are considered more valuable, and they are about 5% of the total amount of this skin.
Galil-AR Sandstorm (Sandstorm)
One of the most affordable skins that have a pattern index that affects value is Galil-AR Sandstorm. The texture color ranges from dark brown to bright yellow. Typically variations of this skin are colored in light gray and dark brown, but yellow-gold variations such as #555 can cost a bit more.
