1983 - Re 1 Experimental Coin

The experimental coin is 25.95 mm weighing 5.85 gms with Security edge. The first coins in this new design and size were issued by the Mumbai Mint in the year 1982 and is amongst the rarest definitive coins. The design is identical to the regular circulation issue; however two horizontal lines were added to both obverse and reverse dies prior to striking. 

The Heaton Mint at Birmingham produced the 1 Rupee coins for circulation in 1985, with the “H” mint mark. Although not clearly marked with a mint mark, this example was produced by the Heaton mint as a “sample” or “experimental coin”, in order to gain approval.
