In this note written by Elizabeth Coombs Adams (1803-1903), which accompanies the pocket, the item is described as a "Dimity
pocket worn for 50 years (probably) by Mrs.
Abigail Adams my Grand
Mother & wife of John Adams. All old ladies wore these under pockets & carried their keys in them." Given the good condition of the pocket, it is highly unlikely that Abigail used this pocket for "fifty years," however. View the online presentation of the pocket.
