Nice!
Looks like it got a good dose of polishing, too.

Really interesting. I never seem to spot die breaks. I've got to teach myself to look for them.

No die breaks, but several die cracks. A crack and a break are not the same thing and the terms should not be used interchangeably

Nice die cracks! I have found quite a few zincolns with die cracks on the reverse, but none as cool as that one. Most of the cracks I find tend to originate from the corners of the memorial building. Obviously a point of weakness on the die. Thanks for sharing!

hey everyone
I just starting collecting error coins and I'm currently going through my collection of old coins I had as a kid. How do you tell the difference between a die crack, die break, or just a scratch. I'm assuming die errors are raised, but I'm having trouble telling whether what I am seeing is raised or indented. I am using a magnifying glass, but still does not seem to help. should I be using something else or is it just a practice thing differentia. ting these? any help would be greatly appreciated and hopefully I can soon post some of the cool stuff I am seeing here as well as know what the heck I am listing, lol

Scratches are incuse or indented INTO the coin. Die cracks are RAISED irregular lines on the coin that are formed from cracks in the die. Die BREAKS are caused when a piece of the die actually breaks off the die and falls away. This creates a raised featureless AREA on the coin and usually a weak area in the same place on the other side of the coin. (In some cases the piece will not fall away and you will have a raised area that weakly shows the design. This is a retained die break. Typically die breaks include part of the edge of the coin and are called Cuds. A retained die break of this type is called a Retained Cud.) Then there are scratches in the die. These are usually straight and cause raised straight lines on the coin. On the coin shown above you will see a lot of die scratches above and below the memorial from coarse polishing. There is a very strong die scratch comeing from the left to the bottom of the you in UNUM Notice how that scratch is straight and smooth compared to the crack coming down through the S. Also die scratchs will usually only be seen on the fields because whatever scratches the die does not drop down into the depressions in the die. Notice how the scratches that go through UNUM go right up to the edge of the letters and then continued on the other side but are not visible on the top surfaces of the letters while the crack coming down through the S is visible on the top surfaces of the letters it passes through.

And a "die error" is a problem that occurs to the die after it is hung onto the minting press and repeats itself from coin to coin until the die is retired. A massive die break at the edge of the die where part of the die falls off and leaves a "blob" of raised metal where that part of the die used to be is called a Cud. This is a die error. Die cracks, chips, and breaks are not generally considered die errors because within some level of tolerance they are accepted as a normal part of the minting process - like with the coin imaged above. All of the design is still there, the coins continue to strike normally with the die, thus the die is left on the press until it wears out or breaks completely. |

Thus the saying: "getting every cent" out of a die pair till they retire.
