worthless opinions

When I paid for my shopping at the supermarket check-out the other day, the assistant rejected one of the coins, telling me it was foreign.

She was wrong: it wasn’t foreign, it was old. Somehow this had got into in my purse:

1967 ship ha'penny coin
I wasn’t wearing my glasses, so I’d handed it over thinking it was a tuppenny piece. It seems my two penn’orth is only worth a ha’penny.
