This 1652 New England Pine Tree Shilling is graded MS65+ from NGC, and just sold for $76,375 in the recent Stacks-Bowers coin auction at the ANA World Fair of Money, held in Chicago. CoinUpdate's article on the sale notes:
While not particularly rare as a variety, this particular coin’s exquisite state of preservation makes it one of the absolute finest known examples of this 17th century coin...
The NGC MS-65+ specimen has a pedigree that goes back over a century, adding to the importance of the piece sold by Stack’s-Bowers at the ANA auction. It was previously in the collection of F.C.C Boyd and the John J. Ford Jr. collection, in whose sale it was included in Part XII, sold in October 2005. Noted specialist and author of the standard reference on Massachusetts silver coinage Sydney P. Noe chose this exact coin in his reference when it was published in 1952 to represent the Noe-1 variety. Without a doubt the sale represented a major coin in American colonial numismatics and an offering that is not repeated easily.
Not bad looking for an over 300 year-old coin!
