Hammer Die: The moving die which is opposite to the stationary (anvil) die. The hammer die moves toward and strikes a planchet resting on the anvil die. Up until the 1990s, the obverse die served as the hammer die, but then the mint began experimenting with using inverse die installation, employing the reverse die as the hammer die, and this has now become the predominent set-up used by the mint.

Hammer Job: See Garage Job.

Hardy Index System: A schematic method for identifying and classifying BIEs and other LIBERTY die breaks. It was developed by Howard O. Hardy for the BIE Oddity Collectors Guild. The index was first applied to over 1800 illustrations of Liberty die breaks drawn by John Gedko. In 1972, a publication called the “BIE Handbook” Edited by Howard O Hardy was released using the system. An explanation of the Hardy Index System can be found on page 21 of the BIE Handbook. Here is an example taken from the BIE Handbook for a 1999-S Lincoln cent.
1. 99S-4CL+7 The year of the coinage.
2. 99S-4CL+7 The mint of manufacture.
3. 99S-4CL+7 The die break locator ( 1L2I3B4E5R6T7Y8 ).
4. 99S-4CL+7 The delimitation letter.  (An indicator of the height/size of the die break)
5. 99S-4CL+7 The die break position letter. (An indicator of the left/right position between the 2 letters)
6. 99S-4CL+7 The extension indicator.
7. 99S-4CL+7 The variation serial number.

Horizontal Mint Mark: In the Lincoln cent series there are a few issues of Lincoln cents that have had a re-punched mint mark, with one of the punchings being sideways into the die. Some generally accepted issues include a 1909S, a 1950D, and a 1961D. A 1955D with a supposed re-punched horizontal D has been de-listed by most attributor.
