The coins have a reverse struck by two different dies (often inverted from each other) but the obverse is normal. The theory is that two reverse die holders alternated at one station sharing the obverse die. Reverse dies tend to fail sooner than obverses because of the protection provided by the lower, anvil position. Being smaller and hit by the hammer would cause the top die to heat up more than the lower so allowing the reverses to cool a few seconds while keeping the obverse in constant use might make sense. Curtis' examples show two different type reverses used but mine seems to be the same type unless the mark before ANTS is a dot on one and a star on the other (unclear to me). What we see here is a doublestrike with the reverse rotated 180 degrees between strikes or an overstrike where the second strike was from a different die held in the opposite position.
