This Trivia is going to show you some error coins you, probably, don't know exist. All photos and text courtesy of Coin Archives unless noted otherwise. You know some countries, including British East and West Africa, had circulating Half Pennies and Pennies with a centered hole like these three beauties struck at the Heaton Mint located just outside London, England: http://www.coinarchives.com/w/lotviewer.php?LotID=599459&AucID=436&Lot=1366 But do you know many of those holed coins are sought-after by error coin collectors? Here's some photos of a few: First British West Africa: http://www.coinarchives.com/w/lotviewer.php?LotID=599455&AucID=436&Lot=1362 http://www.coinarchives.com/w/lotviewer.php?LotID=599476&AucID=436&Lot=1383 British East Africa (3 coins): http://www.coinarchives.com/w/lotviewer.php?LotID=599606&AucID=436&Lot=1513 3 More British East Africa: http://www.coinarchives.com/w/lotviewer.php?LotID=599619&AucID=436&Lot=1526 And now for a modern Coin Error, specifically a Euro coin. Wonder how this error could happen, but more so as to how it could have been released for circulation by the inspectors: http://www.coinarchives.com/w/lotviewer.php?LotID=594203&AucID=433&Lot=21040 And this Euro? http://www.coinarchives.com/w/lotviewer.php?LotID=475706&AucID=351&Lot=52601 Want to see what might happen to a coin if it's struck without the collar in place?
