CELEBRATING THE LEGACY CHINA'S MOON FESTIVAL PANDA® SERIES – For the first time ever, the complete decade of Moon Festival Panda designs is available in a series of exquisite Legacy Sets–each one honoring the innovation and tradition of this beloved series. PRIVY MARKS INCLUDED ON PANDA PROOFS FOR THE FIRST TIME EVER – To commemorate the original date that each Moon Panda design was released, the China Mint has added two-digit number privy marks to each piece that represents the year of release to each design. This is the FIRST TIME Moon Panda Proofs have featured a privy mark!

Each bears the mint's famous e "Z" mintmark on the bottom left side of the obverse. This mintmark is seldomly used for China Panda releases. PERFECT PROOF CONDITION – Each piece in your 2015–2019 One-Ounce Silver Moon Festival Panda 5-Piece Legacy Set has been graded by the Numismatic Guaranty Company (NGC) as being in flawless Proof-70 Ultra Cameo (PF70UC) condition.
