Is 24 carat rolled gold from 1940 worth anything?

24 carat rolled gold is where pure gold is layered onto a base metal, usually silver in the case of 24k gold, and then heated to make the two bond. There were many famous jewelers in the 1940's who used this process to make their products available to the average person and the worth of would be more in who made the piece than the gold in it. The best thing to do would be to take the piece to a trusted jeweler and have them appraise the piece.
