About this case

Where Is This Case Available?

The Gem Mining case is available on skin.club. It contains 11 skins with published drop rate statistics. The Expected Value and drop rate data below reflect current statistical data for this specific case listing on skin.club.

Case Overview

The item pool is narrowly curated, featuring a limited selection of high-demand gem-pattern items supported by minimal lower-tier entries. The distribution is steep, with a clear concentration of theoretical value in the upper tier, while most outcomes fall into significantly lower valuation brackets. This structure emphasizes rarity over diversity, resulting in a sharply skewed hierarchy.

Value and Risk Factors

Expected value is highly sensitive to the drop probability of rare gem-pattern items, which typically exhibit strong and stable market demand. However, the probability mass is concentrated in lower-tier outcomes, leading to high variance and wide dispersion between median and mean results. Liquidity for premium items is generally strong, but their low frequency drives outcome unpredictability. The case reflects a high-variance distribution with heavy reliance on infrequent top-tier realizations.
