The Kolkota Mint opened bookings for this coin in May this year. Yes you are reading this correct, ordered this May and received today. Order was sent on 8.5.2013 and coin set received on 19.09.2013. Item received in a record 5 months. What is amazing is that unlike before where a 2012 coin would be opened for booking in 2013, this is a 2013 coin to coincide with Swami Vivekananda's 150th birth anniversary.
