There are 13 stars, arrows, olive leaves, and olives in the Great Seal of the United States, symbolizing the original 13 colonies.
The design of the seal was approved by Congress in 1782.
As seen on the back of the dollar bill, the seal consists of an eagle holding olives and arrows in its talons, with stars in a nimbus over its head.
In its beak, the eagle holds a banner with the Latin inscription E pluribus unum (“Out of many, one”). The number of letters in that motto is also 13.
