Morgan's coiled hair design in gold, one of about 10 known. These were struck from shaved half eagle planchet stock resulting in the coins having striated surfaces.

It was also part of a goloid set. To view Morgan's set which included this design, click here. The first occurrence appears to be the 1906 Chapman brothers sale of the H.P. Smith collection which is many years later than the other 3 of this type.
Note: Although many reference works state that there are two examples in the Smithsonian, there is in fact, only one example, the Lilly coin.
They were also struck in the following metals.
J1661/P1861 copper with over a dozen are known.
J1662/P1862 aluminum with at least 4 known.
