Occasionally you will find a “double backstamp.” This is when there is an embossed or incised backstamp, and then an ink stamp applied as well to the piece. The double backstamp does not change the value of the piece.
The illustration to the right shows the incised backstamp with the ink stamp on a mug.

You may also find a molders mark on the base of the mug as shown in the illustration to the right. IE “H” (Photo courtesy of Dianne Hutchinson)

The illustration to the left shows just how much a mug shrinks during the firing process.
The greenware/unfired mug is in the back with a fired/glazed mug in the front.

The Amberstone/Casualstone/Fiesta® Ironstone (left) and Vintage (center) mugs do not have the concentric rings at the rim of the mug like the Post 86 (right) ones do, as shown in the above illustration. Also, notice that the Post 86 handle is the same as the Vintage mug handle.
