The Philadelphia mint began producing the familiar Liberty Head half eagle design in 1839. After a quick modification in 1840, this issue continued without change until 1866 when the motto IN GOD WE TRUST was added to the reverse. The branch mint No Motto half eagles from the 1840’s are very popular with collectors. But their Philadelphia counterparts have lagged behind, both in price and level of demand.

During 2009, I wrote a series of “ten rarest” articles on all the major denominations of Liberty Head gold coinage. These articles were well-received and I enjoyed producing them. It’s a logical progression to apply this topic to the early gold series. Except it’s not quite that easy. The eagle denomination is very short-lived (1795-1804) making a ten rarest study impractical.

The 1873 and 1875 gold issues from this mint have received considerable fanfare over the years but I think the Philadelphia gold coinage from 1870 is pretty interesting as well. Having recently sold a number of high quality 1870 Philadelphia gold pieces, I thought it would be interesting to present an in-depth study of these, going from the dollar all the way up to the double eagle.

While I am personally still a fan of collecting gold coins by sets, I understand that this method is not for everyone. Some individuals find set collecting monotonous; others lack the patience to assemble anything but a short set. And other collectors simply do not have the financial resources available to work on a set that might not only have a long duration but may contain many expensive coins as well.

I’ve written numerous articles about Liberty Head gold coins that I think are clearly undervalued or underpriced. I’ve never really written one that’s focused on early United States gold coins for one simple reason: it’s hard to brand coins that trade for $10,000 and up (in most cases) as “undervalued.” That said, there are a number of issues whose price levels do not make sense given their rarity.

In my continuing series that has focused on the ten rarest coins in each denomination of United States gold coin struck from the late 1830’s to the early 1900’s, I’ve nearly reached the end of the road. The last major denomination to discuss is the enigmatic Three Dollar gold piece. This denomination was produced from 1854 to 1889. For more details and history behind the series I suggest that you read the book the Q.
