And Privy Marks!!!!??? That say V75....

From the article:

The privy mark, which is part of the master die for the coins, reads “V75” within an outline of the rainbow pool of the National World War II Memorial in Washington, DC and denotes the 75th anniversary of the allied victory in World War II. It will appear to the left of President Washington’s profile in the center of the left side of the obverse. While these are the second U.S. coins to feature a privy mark after the American Innovation dollars, they will be the first U.S. Mint quarters to sport a privy mark.

Privy marks historically have been grouped with mint marks as each has been used to specify where a particular coin was made. Although while mint marks were first used in ancient Greece to indicate under whose supervision a coin was produced, privy marks date to the 14th century.

English coins made during the reign of King Edward III used secret privy marks to indicate when the coins were made.
