Message:: [QUOTE="Conder101, post: 366269, member: 66"]In the error field, in order to be considered a "cud"  the die break (That's die break where a piece of the die has broken away, not just a die crack) must include the edge of the coin.  Then the cuds can be devided into two catagories, a "Rim cud" which is strictly confined to the raised rim area of the coin, and the "Design cud" which extends out into the field area of the coin and potentially to the actual design of the coin. Why the difference?  Well think about the die.  The field of the die is horizontal and when it reaches the edge of the die you have a vertical drop of a millimeter or so and then a second horizontal surface before a second vertical drop (The side of the die.  This second horizontal surface is what forms the top edge of the rim.  If the edge chips off the die and only takes away this small horizontal surface you get a raised lump just on the top surface of the rim.  (Such as on your coin.  But this chipping is nowhere near the actual coining surface of the design of the die.  A larger piece must break off the side of the die before it becomes a design cud.[/QUOTE]
