In the Department of State, the term "Great Seal" refers to a physical mechanism which is used by the department to affix the seal to official government documents. This mechanism includes not only the die (metal engraved with a raised inverse image of the seal), but also the counterdie (also known as a counter-seal), the press, and cabinet in which it is housed. There have been several presses used since the seal was introduced, but none of the mechanisms used from 1782 through 1904 have survived. The seal and its press were saved when Washington, D.C. was burned in 1814, though no one knows who rescued the pieces.
