The image displays a collection of old Indian coins, specifically various denominations of Paisa and Naya Paisa, which are subdivisions of the Indian Rupee.
Paisa and Naya Paisa:
The term "Paisa" refers to the fractional currency of India, where 100 Paisa make up one Indian Rupee. The "Naya Paisa" (New Paisa) was introduced on April 1, 1957, following the decimalization of the Indian Rupee, and the term "Naya" was dropped in 1964.
Coins in the image:
The coins shown include 25 Paise coins from 1984, 1985, and 1988, as well as 10 Naya Paisa coins from 1957 and 1960.
Legal Tender:
In India, coins issued by the Government of India are considered legal tender, provided they are not defaced and retain their prescribed weight. Fifty paise coins are legal tender for sums not exceeding ten rupees in a single transaction..
