[QUOTE="CappedBustDimes, post: 297743, member: 9104"]i am afraid you are wrong. actually it's quite the opposite of what you have described. after the die is engraved and annealed it loses its ductility and becomes brittle. when cracks, usually around the periphery, form after striking and join adjacent cracks that causes a piece of the die to become dislodged and off plane with the rest of the die. when this happens it causes the affected area on the coin to be raised on the coins surface with some detail remaining-retained cud. when the piece is completely dislodged and no detail is present- full cud in both cases a weak strike is observed on the side opposite the cud because there is no [or very little in retained cuds] pressure being exerted onto the planchet where the cud[/missing piece of die] is present. frank's statements would have been correct if the cud or bulge was already present on the blank planchet prior to striking rather than on the die. here are 2 more examples of the 1836 lm1.2 1836 lm-1.2 [IMG]http://img162.imageshack.us/img162/1999/1836halfdimelm12r5xf45wkv4.jpg[/IMG] [IMG]http://img138.imageshack.us/img138/9155/1836halfdimelm12r5xf45wxs7.jpg[/IMG] 1836 lm-1.2 [IMG]http://img48.imageshack.us/img48/636/1836halfdimelm12vgobv11gm9.jpg[/IMG] [IMG]http://img138.imageshack.us/img138/2348/1836halfdimelm12vgrev11xk3.jpg[/IMG] it is difficult to comprehend and even harder to explain but, a simple exercise with 2 halves of a potato [used as hammer and anvil dies] and some playdo or clay [used to represent the planchet] can help understand die deterioration.[/QUOTE]
