    The U.S. Mint produced a few gold-plated and silver-plated pattern coins and medals. There are several techniques for doing this. Electroplating, foil stamping, and hot dipping are the most common. Is there any record of the technique(s) used by the Mint pre-1933?

    Sure. A couple of images are below. The $4 stella is gilded copper. The large format Norse medal is silvered bronze. Unfortunately, I don’t own them.
