2000-W Gold/Platinum $10 Commem Library of Congress Pf (Box/COA)

---

In the year 2000, the United States Mint marked a major technological and artistic milestone by issuing its very first bi-metallic coin. This innovative ten dollar commemorative piece was struck at the West Point Mint to celebrate the bicentennial of the nation's premier library, the Library of Congress, which was founded two centuries prior. The physical composition of this modern proof coin is its most defining feature. At its core lies a disc containing 0.2509 troy ounces of pure platinum. This central platinum core is encircled by an outer ring containing an equal weight of 0.2509 troy ounces of gold, creating a striking visual contrast of precious metals. The design elements mirror the intellectual theme of the institution. On the obverse, the hand of Minerva, the Roman goddess of wisdom, raises the torch of learning high against the backdrop of the historic Thomas Jefferson Building of the Library of Congress. The reverse features the official Seal of the Library of Congress, surrounded by inscriptions including the face value of ten dollars and the name of the issuing nation.
