Article of the Day
William IV's British coinage, struck between 1831 and 1837, ranged from the double sovereign to the third farthing, though the former was not minted for circulation and the latter only for colonial use. The coins have an obverse (pictured) by William Wyon based on a sketch by Francis Chantrey, and reverses by Wyon and Jean Baptiste Merlen, both of the Royal Mint. Preparation began even before William became king in June 1830, probably because Wyon wanted to head off a potential challenge from Benedetto Pistrucci. Wyon's work was viewed by the king, who liked it and ordered it to be used for all coins during his reign. Final designs were approved in early 1831, and coining began that year. In addition to the issues for use in Britain, several small denominations were struck for colonial use. Two of these, the half farthing and silver threepence, were later issued for use in Britain. William's reign saw no great innovations in coinage, but marked the start of reform at the Royal Mint. (Full article...)

Why you should extend your general knowledge:
There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.
As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
