Just received my Whitman Colonial coins Book!

Here is synopsis of the, "Wood's Rosa Americana Coinage 1717-1733".
Wood was a metallurgist.
He obtained a patent from George I to produce coins for the "American Plantations".
Some sat the Duchess of Kendall helped secure the patent.
The Rosa Americana coinage was made at a time when coinage was scarce.
The patent was for 14 years. No more than 200 tons were struck during the first four years. No more than 10 tons for the next 10 years was to made.
These coins were designated for the, " islands, dominions, or territories belonging to His Majesty, His heirs, or
His successors in America, Or any of them."
The Rosa Americana coinage was given halfpenny, penny, and twopence, but was only about half the weight similar English denominations.
Some coins have been found without silver in them.
Efforts were made to circulate the coinage, but it largely rejected but did circulate. These coins also circulated in England.
