Hi,
Die chips are minor and very common on all Lincoln cents.
The pictures being shown with retained broken dies have value. Die chips are so common as to have no value unless a huge piece of the design is missing.
Cuds involve the rim of a coin. Once in awhile you might find a coin with a nice , very large die chip not involving the rim and that would have value. In that case you would have what looks like a big blob of raised metal in the middle of the coin.
Most times if you find a coin so described, someone melted copper or silver solder onto the coin. So a coin like what I described would have to be seen by someone who can tell what it really is.
Die chips that are miniscule like this one, or ones that cause a digit or letter to be filled are interesting but don't have any additional value.
Thanks,
Bill
