Pattern seeds for Fade items are the primary factor in determining how quickly you can convert your inventory back into cash. While many players focus on the float value, the actual shift of the color gradient across the weapon slide or blade creates a massive price gap between a 90% and a 99% version. I have noticed that even a slightly better purple tip on a Glock can result in a 40% markup on high-end trading platforms. The problem is that the visual difference is often so minor that inexperienced buyers end up overpaying for seeds that aren't actually rare. You need to be able to verify the specific seed number against a known database before you commit thousands of dollars to a trade that might take months to exit.
