How can you test a coin for real gold?
All coins have a specific weight which you can find in coin referencing material per country along with a specific diameter. For example an U.S. 1922 Saint Gaudens Double Eagle ($20 gold piece) weighs 33.436 grams which contains 90% gold. If a coin is not this exact weight and diameter from this specific year then it is not the gold coin in question. If you are not concerned about defacing the coin there are gold testing kits available online or at your local chemical stores. Most use Nutric Acid and Muriatic Acid, which are applied to filed particles from the specified coin. These acids cause non gold particles to separate from gold. There are also electronic gold testers available at rather investment grade pricing.
