I found one Rs.5 coin of 1999 Hyderabad Mint with unusual security edge... similar to the one found in Rs.1 coins of 1992... Is this a variant or error or what ?
Do any one got any idea about it ?

I think no other mint has used such security edge in their mintage...
DO any one has got any more info ?
