Question

Why the lions are shown on our currency notes

Answer 1

If you look at the Ashokan pillar at Sarnath (or a picture of it) you will find the capital of the pillar has 4 lions sitting back to back the bull, the elephant and the galloping horse. The lion represents the attainment of Buddha-hood. The four lions surmounting the capital symbolize the kingship of the Buddha and his roar over the four directions. 

There is also a non-religious interpretation to the symbol, describing the four lions as the symbol of Ashoka rule in four directions. 

Just Buddha his follower Ashoka wanted to spread message a peace and friendship. Similarly India after she gained independence wanted to spread the same message. So India adopted the emblem of 4 lions after she gained independence. We can find this emblem on the official letterhead of the Government of India and appears on all Indian currency as well as cars of the President of India. Prime Minister and other Indian dignitaries. It can also be seen on the epaulette (shoulder ornament on a navy or military officer's uniform) and on the diplomatic and national Passport of the Republic of India.

Answer:

These lions on our currency notes in honor to one of the greatest kings of India ashoka who built the capital. moreover on independence the lion was recognised as the national animal. so the notes also showed the lion capital. another object in which we see these lions are the coins of our currency.
