United Kingdom

The pound sterling is Britain’s millennium-old unit of account: 12 pence to the shilling, 20 shillings to the pound (£sd), struck by the Royal Mint since its origins over 1,100 years ago, moving from the Tower of London to Llantrisant, Wales in 1968. Decimal Day — 15 February 1971 — ended the £sd system and created the decimal pound of 100 pence.

History & collecting

The story behind the coins, one tap away.

  • Issued: bronze pennies, halfpennies and farthings circulated for most of the Victorian through Elizabeth II eras; the classic Britannia reverse pennies (George V bare head / seated Britannia) are the type most collectors hold.
  • Composition: bronze; genuine George V pennies weigh 9.4 g.
  • Key dates (verified only): the 1933 penny — no more than six or seven are known, per the Royal Mint Museum; they were never issued for circulation, struck only for foundation-stone year sets, and one was stolen from the Church of St Cross, Middleton, near Leeds, in 1970 and never recovered. Do not trust raw high-grade examples — altered dates (1932 or 1936 with the last digit re-cut) are a known forgery method, and genuine pieces weigh exactly 9.4 g.
  • Notable varieties (verified only): 1919 with “H” or “KN” mintmarks — coins struck at Birmingham’s Heaton or Kings Norton mints.

Britain rewards series specialists: the £sd silver debasement dates (1920, 1947) are the hinge for everything from sixpences to crowns, and the sovereign is the one British coin that doubles as a bullion position. The two famous rarities here — the 1933 penny and the 1819 sovereign — are also the two most dangerous coins to buy raw, because both are counterfeited; genuine examples are almost always certified, and sovereigns come with Pistrucci’s St George-and-dragon reverse but also legitimate shield and commemorative reverses — weight, dimensions, and a certified holder are the real checks, not the reverse design alone (NGC KM-696). For every value question, work from the linked entries’ live sold listings, not from printed price lists.
