rs 100 Biju Patnaik Birth Centenary Silver Coin rare
The coin is highly valued by collectors because it is minted as a 35-gram non-circulating commemorative piece
containing 50% pure silver alloy
The "1816" Date Error: Because the reverse side accidentally featured the year "1816-2016" instead of Patnaik's actual birth year timeline (1896-2016), its unique error status has sustained premium demand among numismatists.
