Yes, pennies can tarnish in hydrogen peroxide. While hydrogen peroxide is not a strong tarnishing agent, it can react with the copper in pennies over time, leading to oxidation and discoloration. This reaction may result in a greenish patina, especially if the pennies are exposed to air and moisture. However, the extent of tarnishing will depend on factors like concentration, exposure time, and environmental conditions.
