1975 50 Paise Coin Value

The catalogue records 3 catalogued varieties of the 50 Paise for 1975, struck at Hyderabad Mint, Bombay (Mumbai Mint), Calcutta (Kolkatta Mint).

Is the 1975 one the rare one?

Partly. Of the 3 varieties struck that year the catalogue separates 1 Scarce from the rest. Which one you have depends on the mint mark, not the year alone.

Every 1975 variety, by mint

Mint	Rarity	Metal	Weight	Diameter	Thickness
Hyderabad Mint	Scarce	Copper – Nickel	5.00 grams	24.00 mm	1.67 mm
Bombay (Mumbai Mint)	Common	Copper – Nickel	5.00 grams	24.00 mm	1.67 mm
Calcutta (Kolkatta Mint)	Common	Copper – Nickel	5.00 grams	24.00 mm	1.67 mm

Check it against your own coin

Every 1975 variety weighs 5.00 grams and measures 24.00 mm across, circular. If yours is noticeably lighter or smaller it is not a 1975 50 Paise, 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 1975 50 Paise that mark is the whole question, because the year on its own does not separate one variety from another.

What it is worth

The catalogue records no price for any 1975 variety. That is not missing data. It is the catalogue saying the coin was struck in numbers large enough that an ordinary example carries no collector premium, whichever mint it came from.

Scarce is not the same as valuable. It means fewer were struck or fewer survived, which is a reason for a collector to look twice, not a price.

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