"
Cud" is one of those terms that is losing its original definition.
To truly be a
cud the rim has to be involved.
In this case it is a
die chip under the "E".
But
cud is now often used in lieu of
die chip.
The same happened with other numismatic terms and they persist because people understand them.
Eventually (alas!) they will become correct.
One that became correct years ago is the term "penny".
The US does
NOT have
pennies.
Look at the reverse of the coin in this post.
It is a "
CENT".
Another one that may soon become accepted is "double die".
Sorry, the correct term is "double
d die".
But for how long?
