1951 One Pice Coin Value

The catalogue records 2 catalogued varieties of the One Pice for 1951, struck at Bombay (Mumbai Mint), Calcutta (Kolkatta Mint).

Is the 1951 one the rare one?

No. Every variety struck in 1951 is marked Common. There is no rare mint and no key variety for this denomination in this year. That is a definite answer, and it is worth more than a hopeful one.

Every 1951 variety, by mint

Mint	Rarity	Metal	Weight	Diameter	Thickness	UNC (catalogue)
Bombay (Mumbai Mint)	Common	Bronze	2.92 grams	21.33 mm	1.45 mm	₹50
Calcutta (Kolkatta Mint)	Common	Bronze	2.92 grams	21.33 mm	1.45 mm	₹50

Check it against your own coin

Every 1951 variety weighs 2.92 grams and measures 21.33 mm across, circular. If yours is noticeably lighter or smaller it is not a 1951 One Pice, whatever the date reads as.

Weigh it on any scale that reads to a tenth of a gram, and measure the diameter across the widest point. Wear removes very little weight, so a coin more than a few percent off the figure above is usually a different issue rather than a worn one.

Reading the mint mark on your coin

The mark sits under the year. A star is Hyderabad, a diamond or dot is Mumbai, a solid dot is Noida, and no mark at all is Kolkata. On a 1951 One Pice that mark is the whole question, because the year on its own does not separate one variety from another.

What it is worth

2 of the 2 varieties carry a reference price, at ₹50 in uncirculated condition. A coin that spent years in circulation is not that coin.

Every other year and denomination is catalogued here, and this explains how selling actually works.
