To answer you guys questions above, a Clad Proof is a coin that is made of either Silver or in most cases a Nickel Alloy, which is then Platted in 24K gold. This coin is a reproduction of the 1933 Saint Gaudens Gold 20$ Eagle, which were very rare and the real ones are worth Thousands, but of course this a reproduction. Hope I answer you guys questions to the seller for him. I am also a Coin Numismatist and Dealer, so if you would please add me to as a favorite seller I will have my items uploaded and listed very soon also. Thank you!
