• One day, a guest gifted me a US dollar coin and that was the start of my collection. I have more than 1000 coins from 30 countries including Bangladesh Canada, Russia, Dubai, Sri Lanka and Singapore. More than 500 of those are commemorative coins. I bought books that had information about coins and their series. It has helped me understand world history. My favourite in my 25-year-old collection is the ₹2 Braille coin issued by India in 2009, to commemorate the 200 th birth anniversary of Louis Braille. It has his name embossed on it. I own 150 of the Braille coins. I also have 10 paise coins released from 1988 to 1998. I have exhibited my collection in more than 30 schools since 2014.
