Identification of genuine & doctored 1996 Subhas Chandra Bose 2 Rupees issue: IN ORDER TO DIFFERENTIATE BETWEEN GENUINE & DOCTORED 1996 SUBHAS CHANDRA BOSE 2 RUPEES COIN, ALWAYS LOOK FOR THE BORDERS OF THE COIN. IN CASE OF 1996 ISSUE THE BORDERS ARE VERY THICK AND IN CASE OF 1997 ISSUE THE BORDERS ARE THIN, THIS MEANS IF A 1996 ISSUE IS GENUINE THEN IT SHOULD HAVE THICK BORDERS AND IF THE ISSUE IS DOCTORED ONE (WHEREIN 1997 ISSUE WAS ALTERED TO 1996 BE MISCHIEVOUS PEOPLE) THEN IT WILL HAVE THIN BORDERS AS SIMILAR TO 1997 ISSUE. ALWAYS REMEMBER, LOOK FOR BORDER COMPARISON ON THE PARTS, WHERE THERE ARE NO SHIFTING ERRORS.

of coins for auction and sale.

One of my most favourite groups is the:

British India and Republic India Coins Tradings
