1980 25 Paise Coin Value
The catalogue records 6 catalogued varieties of the 25 Paise for 1980, struck at Bombay (Mumbai Mint), Calcutta (Kolkatta Mint), Hyderabad Mint.
Is the 1980 one the rare one?
Partly. Of the 6 varieties struck that year the catalogue separates 3 Scarce, 1 Ultra Rare from the rest. Which one you have depends on the mint mark, not the year alone.

Check it against your own coin
The 1980 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 1980 25 Paise that mark is the whole question, because the year on its own does not separate one variety from another.
What it is worth
3 of the 6 varieties carry a reference price, from ₹75 to ₹150 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.
