The final value of vintage costume jewelry stick pins depends on a few specific details:

• Materials: Standard base metals finished with a gold-tone plating typically sell on the lower end ($9 to $15). If the pin carries stamps indicating a higher material value—such as being gold-filled (e.g., 1/20 12K GF) or solid gold—the price increases significantly based on the metal weight and purity.
