To circumvent these difficulties the Royal Mint adopted a special tool method. This consignment was brought to Sri Lanka in the early hours of 1st February 1978 by T. M. U. Sallay (Senior Assistant Superintendent of Currency and author of book "Sri Lanka Currency of Recent Times 1938-1985") who had been flown earlier to London in this connection. More... The effigy on these 2600 special coins is slightly different from those on the balance of the order. The most noticeable difference is the shoulder line of the President's image. In this rare coin shown above it is comparatively straight, while in the standard coin shown on right it curves upwards.

According to Sallay, who I had the pleasure of meeting in Colombo in Dec 1999 the choice of denomination was based on the availability at that time of 1 rupee blanks at the royal mint. The obverse was to be the same, and the artwork for the reverse was done independently by two artists. One of the original dies was used to produce the small initial consignment and got worn out in the process, and the other slightly different die replicated to make the coin dies used to mint the rest of the 2 Million coins.
The special issue of 2600 coins is not a Proof as listed sometime ago in Krause. It is significantly rare since most of this 2600 released into circulation got mixed with the 2-million before it was realised to be different from the rest. Most known are from those kept by collectors on the day of issue. A few have been reported as having been found from circulation.

Included in that small consignment were 30 minted as gold frosted Proof coin.

The coin was scanned at 300dpi and the images are displayed at 250dpi. The special rare JRJ coin was a very kind gift to me from Thun Sallay.
