VICTORIA 1858 Farthing 8 over 7, broken 5 & 8 in date

By looking carefully you can see the whole date has been re-punched from 1857 to 1858, the 7 being well disguised. I have seen an 8 over 7 before somewhere for sale in the past, but cant recall where. Its obviously very rare, i do believe theirs probably more as many go unchecked.  Farthing grades good very fine with a scratch on the obverse.
