In the early days of the Republic, the five dollar denomination was considered the most utilitarian gold coin for uses at home and abroad.
Early half eagles are roughly divided into two design types, the Small Eagle and Heraldic Eagle. Of the two, the Small Eagle is the earlier and by far the most desirable (as well as rarer) of the two types.
There are 12 varieties of the 1795 Small Eagle design, only one of which is an extreme rarity. The BD-3 is the most plentiful Small Eagle five from this year with an estimated 200 examples extant. This, of course, makes the BD-3 1795 a perfect type coin.
