Paul Revere Cut Signature
 
The reason his signature is so valuable is because not many exist. He was never a politician so he didn't have to sign documents such as land grants like other popular politicians did at the time. Paul Revere is best known for his "Midnight Ride" where he is famously depicted saying "The British are coming!" That phrase was to alert the American troops the British were on their way to attack which was the credited as the first battle of the Revolutionary War of Lexington and Concord. What most people don't realize is that Revere was a master silversmith and silver spoons he made are extremely sought after.
This example is an extremely nice example of Paul Revere's signature. The entirety of the signature is on the cut which has been authenticated and encapsulated by PSA.
