1988 50 Paise Coin Value

The catalogue records 9 catalogued varieties of the 50 Paise for 1988, struck at Noida Mint, Bombay (Mumbai Mint), Calcutta (Kolkatta Mint), Hyderabad Mint, Ottawa.

Is the 1988 one the rare one?

Partly. Of the 9 varieties struck that year the catalogue separates 3 Scarce, 1 Rare from the rest. Which one you have depends on the mint mark, not the year alone.

Check it against your own coin

The 1988 varieties do not all weigh the same, which makes a kitchen scale the fastest way to tell them apart: the table above gives the weight and diameter for each. Match the weight first, then the mint mark.

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 1988 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 1988 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.
