The Mint used two different style 3 digits to strike the date on 1873 Indian cents. The first date style is referred to as the 1873 Closed 3 and the second style is referred to as the Open 3.
The Closed 3 variety can be distinguished by the 3 digit on the date, as it is thicker than the Open 3 style. On the Closed 3 variety, the ball serifs on the inner central part of the 3 digit are also located closer to one other, making the 3 on the date appear like an 8 digit. The 1873 Indian Cent with the Closed 3 style was the first variety used from the two different varieties. The Closed 3 style is also scarcer than the 1873 Open 3 variety.
