Coins become dirty due to exposure to various environmental factors, including air, moisture, and pollutants, which can lead to oxidation and tarnishing. Handling coins with bare hands can transfer oils and dirt, further contributing to their grime. Additionally, coins can accumulate contaminants like dust, grime, and chemicals from circulation or storage in unclean environments. Over time, these factors can result in a buildup of dirt and corrosion on the coin's surface.
