Hi Liz,

What you are seeing on the date is die chips. On the top of the head and above, it appears to be a combination of die cracks and lamination issues. The base of Lincoln's shoulder looks like a retained die break.

thanks so much, I'm working on my terms here!

They used those dies until they were ready to fall apart back in the 50's

Nice find... The one on the shoulder may be a retained cud and a lamination not sure though... Also does the MM have a split in the lower serif???

thanks so much, I'm working on my terms here!

These terms are all defined in the glossary for your reference.

Die Chip: When a piece of the die breaks and falls off, the subsequent coins struck by that die will show a raised unstruck portion that usually looks like a “blob” of extra metal on the coin. This is simply from the metal flowing into the opening in the die during the strike.


Die Crack: A fissure in the die which will result in a raised line on a coin that is struck by that die.


Lamination Error: This is when metal cracks and flakes off of the surface of a coin, due to impurities in the alloy mixture. These occur almost exclusively on solid alloy coins, and are therefore found on pre-1982 Lincoln cents. The flaking piece may still be attached (retained) or can be missing.


Retained Interior Die Break: This is an interior die break that hasn’t completely fallen out of the die. Since the piece hasn’t fallen completely out, some design elements may still be seen in the area on the coins it strikes, even though there may be lateral or elevation shifts. Please visit cuds-on-coins.com for listings of retained interior die breaks. Photos donated by Bella.



On a side note, Since you do not have private messages enabled, I tried to email you about the usage of your pictures in this thread: http://www.lincolncentforum.com/foru...hlight=rippled for use in the glossary to add the term "rippled coin." Please let me know if we may use your photos for a new entry. You will be credited in the entry. Thanks, Liz.

thanks! to my untrained eye, it doesn't seem to have a split in the MM
