They are from the Philadelphia Mint and are in the states of Georgia, New Jersey, Delaware, Connecticut & Pennsylvania. They are not copper in color but are in fact the same color as the “Gold” Dollar. I have attached a picture for you to see. Did they make a “Gold” commemorative set or something?
Your picture shows a regular quarter that has been gold plated. This is not an error, i.e. struck on a dollar planchet. If that were so there would be a larger border around the coin, the dollar planchet is larger. You can prove this by simply weighing the coin. A standard clad quarter weighs 5.67 grams.
Gold plated coins are a promotional item, have no collector value, and don’t receive an additional market premium for being plated. Note that gold plating coins for advertising, promotions and high school electrolysis experiments have been going on for some time.
