1839 Adam Eckfeldt Retirement Medal. By Moritz Furst. Julian MT-18. Bronze. MS-64 BN (NGC). 52 mm. Attractive and original autumn-brown with slight marbling of trivially deeper color. A few obverse spots are noted, the only apparent impediments to a Gem Mint State rating. A very handsome piece, struck to mark Chief Coiner Adam Eckfeldts long career with the Philadelphia Mint. This is perhaps the most prized type in the Mint and Treasury series.
