Coins of the pound sterling chronologically. All genuine UK coins are produced by the Royal Mint. The same coinage is used across the United Kingdom: unlike banknotes, local issues of coins are not produced for different parts of the UK. The pound coin until 2016 was produced in regional designs, but these circulate equally in all parts of the UK (see UK designs, below). Every year, newly minted coins are checked for size, weight, and composition at a Trial of the Pyx. Essentially the same procedure has been used since the 13th century. Assaying is now done by the Worshipful Company of Goldsmiths on behalf
Coins of the Ukrainian hryvnia coins exist in denominations of 1 kopiyka (i.e. or ₴0.01), 2, 5, 10, 25, 50 kopiyok, ₴1.00 and ₴2.00. Also minted are bullion (including gold, silver and platinum) and commemorative coins. All of these are produced by the National Bank of Ukraine. In October 2012 the National Bank of Ukraine announced that it is examining the possibility of withdrawing the 1 and 2 kopeck-coins from circulation.[5] The coins had become too expensive to produce compared to their nominal value. Also, on 26 October 2012, the National Bank of Ukraine announced it is considering the introduction of a 2 Hryvnia coin.
