Error Twopence 2007?!? (Brit Coin)

Are you referring to the two Cuds at 6:30 and 7:30 on the reverse?
And if you are talking about them, can you tell me if they are solid?
Or are they hollow enough to flake off?

I have a 20p with something similar where the hole should be for a 6 on the date. Don't think it is anything too special, but the coins are not normally errored.

I believe they are more commonly called 'die chips.' My understanding is that a ' Cud' is a specific type of die chip that extends to the rim of the coin. The rim is a common location for the die to break, and the area fills in with metal, making a raised 'cud.'

Definition of a Cud:

A Cud is a damaged area resembling a blob on the surface of a coin which is raised above the field
a little, and which obliterates the device or inscription where it appears. Cuds are the result
of die cracks which have become severe, or from die chips where part of the die surface has
become damaged and broken away.

Some experts in the error-variety hobby insist that for the blob to be called a Cud, the damaged
part of the die must include part of the edge of the die. Although this is the purist definition,
in common parlance you'll see the term " Cud" used to describe the blob created by any die chip or
serious die crack, regardless of its placement on the die or coin.

Very small Cuds are not usually valuable unless they appear on Proof coins. Cuds which can be seen
by the naked eye are usually worth a small premium over normal value, and some Cuds have actually been
cataloged and are collectible, such as those on Morgan dollars or between the letters of LIBERTY on
Wheat Cents.
