I added this unique piece to my collection a few months ago when I won it at auction! I think this coin is so cool! It is a 1783 Nova Constellatio Pattern Coin. Pointed Rays, Small US. This one is graded by PCGS as Genuine with Environmental Damage-VF Detail. I researched for more information on this piece, but didn't find out to much. What I did learn was that it represents one of the first patterns for coinage in the United States. It was designed by Benjamin Dudley for Gouverneur Morris to carry out his ideas for a decimal coinage system. These pattern pieces were the first attempt at a decimal ratio and were the forerunners of our present system of money values. Ultimately these coins never advanced beyond the pattern stage. These all had the date of 1783. That's it folks...and most of that came from the Red Book. All I know is that is beautiful and very old! If anyone can add more information about this coin please feel free to do so. Thanks for your comments!
