Description & Analysis

The reverse of nearly all Chalmers shillings depicts two birds fighting over a worm, a design that has become iconic for Colonial Maryland numismatics. Researchers have long speculated on the meaning of this motif and some theories hold that it represents the American Revolution or, perhaps, infighting between the newly independent states.

Both long worm and short worm varieties are known with the long worm variant being slightly more common. An extremely rare Chalmers shilling type features 12 interlocking rings as the reverse design.

John Chalmers, an Annapolis, Maryland, silversmith struck silver threepence, sixpence and shillings in 1783, the year that the Treaty of Paris officially ended the American Revolution. These coins clearly circulated in Colonial Maryland and examples are seen in a wide range of grades.

The initials “TS” on reverse dies used to strike Chalmers sixpence are for Thomas Sparrow, the engraver of that die and possibly all of the Chalmers coinage. Sparrow was also an engraver of Maryland paper money.

NGC Price and Value Guides Disclaimer

Disclaimer: The prices listed in the various NGC Price and Value Guides are compiled from a number of independent, third party sources in the numismatic community which NGC believes to be reliable. Prices provided are averages, not specific prices for individual coins. Further, because these prices are only updated from time to time, they do not reflect short term pricing trends, which are quite common and are often quite dramatic, given the volatile nature of the collectible coin marketplace. This is especially true for rare coins, where there are fewer sales and greater variations in sale prices. For all of these reasons, the prices in these guides are designed to serve merely as one of many measures and factors that coin buyers and sellers can use in determining coin values. These prices are not intended, and should not be relied upon, to replace the due diligence and — when appropriate — expert consultation that coin buyers and sellers should undertake when entering into a coin transaction. As such, NGC disclaims all warranties, express or implied, with respect to the information contained in the NGC Guides. By using the NGC Guides, the user agrees that neither NGC nor any of its affiliates, shareholders, officers, employees or agents shall have any liability for any loss or damage of any kind, including without limitation any loss arising from reliance on the information contained in the Guides.
