$2 1963 Legal Tender DUAL AUTOGRAPH : Granahan + Dillon Red Seal Deuce Ch CU

Kathryn Granahan was an American politician. She served as a member of the U.S. House of Representatives from Pennsylvania and as the Treasurer of the United States, having been appointed by President John F. Kennedy.

Granahan was a member of the Democratic Party and was the first woman to be elected to the United States Congress from Philadelphia.

Clarence Douglas Dillon was an American diplomat and politician, who served as U.S. Ambassador to France and as the 57th Secretary of the Treasury. He was also a member of the Executive Committee of the National Security Council during the Cuban Missile Crisis. 

Interestingly, this red seal deuce bears the expected dual autograph, but curiously, Dillon signed twice above his engraved signature. It's the first time we've seen this, so it's a bit unusaul, but very cool!
