A 1927-D double eagle is one of the highlights of a sale at Heritage Auctions in Orlando, Florida on January 8-12 with a starting bid of $850,000.
The MS66 graded coin will be highly sought after, with only one finer example known: that MS67 graded coin sold for $1.4m at Heritage in 2010. Around 12-13 specimens from 1927 are known to have survived to the present day, with just seven on the market.
Sculptor Augustus Saint-Gaudens was commissioned by Theodore Roosevelt in 1904 to create a beautiful American coin - a task he completed before his death in 1907.
The example featured in the sale is defined by its clear strike and sharp definition, marred only by minor contact marks and a die crack through the eagle's beak and Liberty's torch.
It sold in 1984 for $2,000, and again in 2001 for $577,500, equating to a 39.5% pa rate of return.
The Saint Gaudens coin was minted from 1907 until 1933, with the issue from that final year considered the rarest of all - due in large part to the gold recall of 1933, which required the American public to hand over their gold to the government in return for paper money.
One example from 1933 sold for $7.6m at Sotheby's New York in 2002.
