Searching some recent coins I discovered four of these 2021's that have different stages of die cracks.
Awesome find !! @GARY R COYIER . I'm a little lost today. Can you tell me simply what the difference between a Die Crack vs Die Break??
I am no expert like we have here, but I would say a die crack is caused by the die cracking under pressure and coins filling and causing a raised line or cud. Interior die breaks are often connected to die cracks. Hopefully someone with more expertise will comment.
No difference except the spelling or terminology. A die crack occurs when a die, after being subjected to immense pressure during the minting process, cracks, causing a small gap in the die. If the damaged die continues to produce coins, the metal will fill into the crack, thus revealing a raised line of metal in the finished coin. If a die breaks it usually starts with a crack. If a die cracks it’s in the beginning stages of breaking.
