It is an RIDB and in a common place for it.
From Error-ref:
Quote:
Definition: An island of metal surrounded by a die crack that sinks into the die face. On the coin it's seen as an island of design that sits on a low plateau. It's almost impossible to determine if a retained interior die break is actually detached from the remainder of the die face or simply sank in as the result of subsurface deformation beneath a cracked surface.
That "plateau" is why it is often confused with a lamination error as it appears to be a planchet flaw, or a separation of metal. The key words in the definition are "sinks into the die face". That means it creates a raised area on the coin.
A "sunken die" or die subsidence is wholly different.
I hope that helps!
