The first issue of coins was in 1709.
The coins were cast and quite crude. High grade coins are quite difficult to find.
Here is the penny and halfpenny in my collection.
Although there was a pattern made in 1723, there was not an official issue. The next was in 1733. There was a penny and halfpenny. There are many varieties of both. These are some that are in my collection
This is the frosted cap variety
The next issue was in 1758. Once again penny and halfpenny, and again there are varieties. There is also thought o have been a restrike later using dirty dies.
As with the previous issue there are contempary forgeries.
