<p>[QUOTE="Publius2, post: 7853284, member: 105571"]There was a recent thread that questioned the inclusion of William Woods' Hibernia coinage under the heading of "US coinage". Here is a coin produced in England by William Woods under royal patent (George I) for the express purpose of circulation in the American Colonies: It is the 1723 Rosa Americana Penny. Woods struck farthings, halfpennys, pennys, twopence and shillings in this style and they most certainly did circulate in the American colonies.</p><p><br /></p><p>Interestingly, this coin is not pure copper. Rather it was supposed to be an alloy called Bath Metal, a mixture of 75% brass, 24.73% zinc, and 0.27% silver. Metallurgical analysis has shown no silver so Woods cheated - imagine that? There is some evidence to suggest that these coins, due to their hardness, were struck after the planchets were heated and were struck using a drop hammer machine.</p><p><br /></p><p>This one was picked up in a Heritage auction a couple of days ago. The photos are Heritage's. I possibly overpaid for this but in my defense, this die marriage is the considerably scarcer Martin 2-F with a rarity rating of URS-4. The other 1723 penny is the Martin 2-E, rarity URS-11. How can you tell the difference? The 2-F has a dot after the date whereas the 2-E does not. What does the Universal Rarity Scale say about these ratings? An 11 means 500 to 999 examples surviving. A 4 means 5 to 8 surviving examples.
