What is the best way to tell the difference in a die crack and a PMD crack? Any secrets to this?

A die crack creates a raised bit of metal on a coin. The metal 'flows' into the die. How can raised metal be duplicated after minting? I do not know.

A die crack happens on the die (Negative) and shows on a coin raised from the surface. (Positive)  The raise up more on the coin called chips when more of the die crumbles away like you see on the 12 column on this image. A PMD/PSD coin will be incuse on the coin (damage)   On this coin a bag mark made an incuse mark into the coins surface.  This was a scratch into the coin surface. Note the nick on the rim.

Negative? Positive? Sounds like a photographer wrote this! Great explanation Coop.

All suffer the same events. I've seen from 1-9 different die cracks on a coin.

I just don't have any images on my image host right now. (almost 4,000 images and not one other than cents.)

Wouldn't that 1799 coin be best described as a broken die and not a die crack? John1

Some time ago another CCF member had a similar example. I found this to compare. I would ask, "Is a broken die the inevitable outcome of a cracked die being used until it breaks?"

It might be a Retained Cud. Note the miss alignment. Nice find.

Disclosure: I 'found' this 1799 example by searching auctions on the Internet and not by a purchase. BUT, it has clued me to notice striking anomalies on coinage. One good thing about Charlie Barber's design is that it had few problems. I did find a nice 1896-S dime with die chips:  Any comments Coop?
