The Dutch Government in Ceylon Surrendered to the British Forces on 1796 February 14th and Ceylon was made a part of the United East India Company - Madras Presidency, until it became a British Crown Colony in 1802.
Perhaps a preliminary pattern struck in copper for the Ceylon copper coinage of 1802. At the time initial inquiries were made for an English minted coinage, Ceylon was nominally under the control of the V.E.I.C. The obverse designs are from normal dies used for the V.E.I.C.'s One 48th of Rupee from the Madras Presidency struck at Soho Mint Birmingham, England for the United East India company resulting in 1794 and 1797 patterns. The Arcot Rupee being counted as a Rix Dollar (12 Fanams or 48 Stivers). It was stuck to the same weight of the Dutch Stuiver and was known as a Dub.
One and Two Rix Dollar Silver patterns for the Ceylon Government dated 1812 not issued to circulation. Designed few Years after the Last of Silver Rix Dollar Dump coins issued in 1809. Also preliminary lead patterns of only the reverse of same with a blank obverse.
A Fanam, 1/12 Rix Dollar patterns for the Ceylon Government dated 1815. Struck in both Lead and Copper (OverStruck on VOC Duit). Designed soon after the undated Silver Fanam token issued in 1814.
Royal Mint, London, had received orders from the treasury to strike silver rix-dollars with effigy of George III and with year 1815 which never reached completion and only a few proof pattern exist.
