British 1970 5 New Pence Struck on Split Planchet

5p coin struck on an underweight blank. The planchet split in half parrallel to the face of the coin prior to the coin being minted, tell-tale metal striations can be seen on the obverse. The coin was struck after the split occurred. Weight is 2.76g, almost exactly half of the 5.65g a complete coin should weigh. It shows extreme strike weakness due to the very thin planchet.
