The coin in question is a 2009 $10 (Ten Dollars) Gold First Spouse coin, a notable piece from the United States mint commemorating the First Spouses of American presidents. Manufactured with a composition of 99.99% gold, it weighs 15.55 grams and has a diameter of 26.5 mm. Designed by Donna Weaver and Thomas Cleveland, this mint strike coin features a reeded edge and is part of a limited mintage of just 3,645 pieces, making it a sought-after collectible among numismatists and investors alike. The absence of a mint mark further emphasizes its unique nature, as it signifies its production without a specific minting location. With its historical significance and fine gold content, this coin is an excellent addition to any collection, celebrating both American history and the artistry of coin design.
