This is a very rare 1999 silver proof set made by The Washington Mint. It commemorates the first year of the US Statehood quarter series. These silver proof coins are in BU/MS shape and all paperwork is included. Only 20,000 sets were made and each coin comes with a certificate of authenticity. Please note: These are not quarters. These coins are large and weigh 2oz each. 5 coins total, 10oz of. Feel free to send me a message with any questions you may have.
