Gold melt value is the intrinsic market value of the pure gold inside an item, ignoring design, brand, and retail markup. This metric helps you set a rational floor price before selling old jewelry, compare multiple buyer offers, and understand the difference between collectible value and raw metal value.
Most "cash for gold" offers are below calculated melt value because refiners include processing cost, risk, and margin. Knowing your melt value first gives you a strong baseline to negotiate confidently.
