Did you know the Star of David is pictured on the back of every U.S. One Dollar Bill?
Curiously, the Great Seal of the United States appears to contain an image of a Star of David, consisting of 13 smaller American Stars symbolizing the 13 original colonies, above the eagle’s head.

It’s not clear what the hexagram meant at the time of the American Revolution, so to attribute some intended national symbolism to it based on today’s meaning is mere speculation. The hexagram shape of the constellation of stars on the Great Seal may have simply been a rearrangement of the 13 stars on the first American flag.
