Coins minted from 1862 through 1873 all have the date 1862.
The legend reads "Victoria Queen" for coins dated 1862 - 1876.
It reads "Victoria Empress" for coins dated 1877-1901.

The 1/12 Anna was minted through 1901. The Madras mint only made 1862 coins, while the Bombay mint was used through 1889 (Krauss lists an 1890 P/L restrike). Only the Calcutta mint produced coins from 1890 to 1901. There are two obverse types.

Type A - The front of the dress has 4-1/3 panels. The bottom complete panel has one flower at its center.
Type B - The front of the dress has 4 panels. The bottom panel has one flower on the right.

Position of the legend "Victoria Empress" from 1877 (see photos below):
Type A - At lower right, the legend is close to the bust.
Type B - At lower right, the legend is far from the bust.

Reverse - the same reverse design was used for the entire series.

Mint-Mark - The 1882-1887 Calcutta 1/12 anna coins have a tiny incuse "C" mint-mark. See note at the bottom of the Checklist page. This mint-mark is tiny and can be seen on only some coins. Possibly the mint-mark was not applied to all Calcutta coins. However, the Calcutta minted coins can be identified by the Obverse type.
