Quarter farthing The British quarter farthing (d) coin was a unit of currency equaling one sixteenth of a penny ( of a pound sterling). It was produced for circulation in Ceylon in various years between 1839 and 1853, with proof coins being produced in 1868. It is the smallest denomination of pound sterling coin ever minted. The coin is considered to be part of British coinage because it has no indication of what country it was minted for, being made in the same style as the contemporary half-farthing
Penny Venetian Red of "POSTAGE" and "ONE PENNY" that its predecessors bore. It was decided that a new colour would also be desirable to defend against improper re-use; a fugitive lilac ink was used that would run and spoil the stamp if one attempted to wash off the cancellation. The Lilacs broke the tradition of using corner letters and instead had either fourteen or sixteen dots in each corner. Penny Venetian Red The Penny Venetian Red was a British postage stamp equal to the value of one penny. Issued in 1880, it was designed and surface-printed by security printing company De La Rue.
