These coins are absolutely beautiful. Big, bold, wonderful Miss Liberty design comes from sculptor Augustus St. Gaudens.
If you have a modern gold reproduction dated 2009, the values on this page do not apply. Instead, see our alternate appraisal page for coins dated 2009 here.
As of the last time we updated this appraisal page (see date above), the Grey Sheet, a conservative US coin price guide, quotes values starting at $1600 US dollars for the most common coins in average circulated condition to $2000 to $10000 for fully, absolutely uncirculated pieces.
Most of the dates fall into the price range just stated. You can figure an approximate price for these coins by adding $150 to the base gold value. A $20 gold piece contains 0.967 troy ounces of gold, so multiply the current gold price (find it at Kitco.com) by 0.967 and you have the base gold value. Now add $150 to get a ballpark retail price for a *garden variety* date. If you happen to have a coin that is fully, absolutely uncirculated, add $300 to the gold value, not $150.
There are coins that are far from *garden variety*. They are the exceptions, and Nina has one of them.
A 1908S coin is worth about three times what a normal St. Gaudens is worth, starting in the catalogs at $2700 in average circulated condition and rising above $20000 in uncirculated.
A 1907 coin with the date in Roman numerals (MCMVII) is very special. The Grey Sheet says $7700 in average circulated and $26000 in uncirculated. Zowie!
NEVER CLEAN A COIN. CLEANING RUINS VALUE.
As with all valuable collector pieces, you must be aware of counterfeits. There are oodles of counterfeits of St. Gaudens gold pieces, and you might have one of those. If you bought the coin on eBay and it is not in a numismatic holder, it could very well be a counterfeit.
After reading the bit of advice in the prior paragraph, Nina sent us a photo of her coin. Compared to the real McCoy in the composite picture, it is obvious that Nina has a counterfeit piece. Not only is the surface inferior to a real gold coin, the design itself is completely different, bearing only a faint resemblance to a genuine design. This counterfeit is obvious. There are several counterfeits that can only be differentiated by a skilled numismatist with a microscope. When buying St. Gaudens gold pieces, deal only with people you trust. See this page for more info on fakes.
If you are interested in getting your coin placed in a holder, which would protect it from the elements and settle the counterfeiting issue, look up the following grading services on the Internet: PCGS, ICG, NGC, and ANACS. Do not use other services.
