Official State Seal of Pennsylvania
The state seal of Pennsylvania has two faces: the obverse is most often referred to as the "state seal;" the reverse, or counter-seal, is used less frequently to authenticate documents. All State Seals
The main face of the seal is identical to the coat of arms, without the horses. The shield displays a sailing ship (carrying state commerce to all parts of the world), a clay-red plough (signifying Pennsylvania's rich natural resources), and three sheaves of wheat (suggesting fertile fields and Pennsylvania's wealth of human thought and action).
To the left of the shield is a stalk of Indian corn; to the right, an olive branch (signifying peace and prosperity). The shield's crest is an eagle; and the design is encircled by the inscription "Seal of the State of Pennsylvania."
The counter-seal portrays liberty vs. tyranny. A woman represents liberty; her left hand holds a wand topped by a liberty cap (a French symbol of liberty), her right hand holds a drawn sword. She is trampling upon Tyranny, represented by a lion. The entire design is encircled by the legend "Both Can't Survive."
