An August, 1797 issue of the London Gazette announced the new coinage of one and two pence pieces (Cartwheels).
My copy of that edition is framed (behind glass), so my scan is not very clear. To make it a bit more readable, I'm showing it here in greyscale. The actual wording is shown way below.

P.S. There is a Tax Stamp in the lower right corner of the newspaper. It is shown enlarged at the top of this page. It was this Tax, applied to both English citizens and to Colonists, that got the Colonists very riled up.
