The set has never been opened and is still in its original factory packaging, ensuring that it is untouched since then. Proof Mintage of the first five of both copper and silver was 10,000 each. Proof Mintage on the last five was only 2500 each. Don’t confuse these with the bullion finish, which had mintages between 34,000 and 50,000 for silver and between 59,000 and 130,000 for copper. These are the proof versions with boxes and COAs for each!
