Ron Guth: 1839 saw the third consecutive year of issuance of the so-called Gobrecht Dollar. Alas, it was also to be the last year for this majestic coin, for in 1840, the "flying eagle" reverse would be replaced with a more conservative eagle adapted from the gold coins of earlier years.
Surprising, isn't it, that the two foundations of our nation's monetary system - the Silver Dollar and the Eagle ($10) - were absent from the numismatic scene for over three decades, neither to re-appear again until the late 1830s.
