1976 20 cent with a mostly split planchet but the two halves have not detached. Planchet split around about 90% of the coin’s rim, the two halves are well separated giving the characteristic clamshell appearance. A previous owner of the coin has encouraged the separation through mechanical means and as a result there is some damage to the rim.
