The image displays a collection of old Indian 10 and 20 paise coins, with various years of minting visible, including 1986, 1988, and 1989.
10 Paise Coins:
These were a former denomination of the Indian Rupee, with 10 paise equaling 1/10 of a rupee. The last issue of the 10 paise coin, minted in stainless steel, was introduced in 1988. Earlier versions from 1957 to 1967 were made of copper-nickel and some read "naya paisa" to distinguish them after decimalization in 1957.
20 Paise Coins:
These were also a denomination of the Indian Rupee. The image shows a 20 paise coin from 1986.
Demonetization:
Coins up to 25 paise, including the 10 and 20 paise coins, were demonetized in India on June 30, 2011, meaning they are no longer legal tender.
Legal Tender Status of Coins:
While these specific coins are no longer in circulation, the Reserve Bank of India (RBI) has stated that all denominations of coins currently in circulation are legal tender, and reluctance to accept them is incorrect.
