Double Crowns - Brief History
We five a very short potted history of the Gold Unite on its own page, the history of the Half Unite is even shorter, as it was not issued as early as the Unite. One interesting, but rather academic question which we find ourselves asking is "What is the difference between a Half Unite and a Double Crown?" We must admit that we didn't know the answer, and had to do some research. Who knows, but another 40 years and we might become experts!
Actually, about ten minutes after writing this, we found the answer, which lies in the legends (the writing is on the coin, not the wall).

Descriptions
Most half unites, like unites, have a typical portrait of the King, with a large crowned shield on the reverse.
The legend (inscription) on the reverse appear to be what distinguishes a Unite from any otherwise similar denomination. This reads:
FACIAM EOS IN GENTEM UNAM, which translates from Latin to English as "I will make them one nation".
Of course, this answers the question we posed ourselves only a few minutes ago. We must stop talking to ourselves, except we do seem to learn from it.
The legend on the reverse of a gold Double Crown reads:
HENRICUS ROSAS REGNA JACOBUS , which translates as "Henry (united) the roses, James the kingdoms"

Fractional & Multiple Unites
As with most denominations, there were fractions issued; these were the Half Unite, but there was no Quarter Unite. There were also multiple Unites issued; these were Double Unites and Triple Unites.
In the Scottish coinage of James VI of Scotland, there were Units, Half Units, and a Quarter Unit, which all help to add to the confusion.
