Rim-restricted design duplication is, as far as I know, restricted to the face struck by the hammer die. In this case, the obverse design was almost certainly struck by the anvil die. Furthermore, RRDD would, in this case, involve the nearest letters, which would be the LAR of DOLLAR. And they would not be raised within a surrounding recess. So, while the appearance of this coin is very strange and currently inexplicable, its features do not comport with anything that could emerge from a coining press.
