60 Rupees BITS Pilani

Issued to mark the diamond jubilee of BITS Pilani's deemed university status, granted in 1964 when the institution was reconstituted under the patronage of G.D. Birla. The 60-rupee denomination directly tracks that anniversary — an unusual face value produced specifically because Indian commemorative rupee coins are routinely assigned denominations corresponding to the years being celebrated.

The .500 fineness is characteristic of modern Indian commemorative silver, a standard the mint has used across dozens of similar issues since the 1990s.
