Awwal 02, 1432 H/April 6, 2011, SPA -- The Royal Canadian Mint has unveiled two kinds of collector coins commemorating the wedding of Prince William and Kate Middleton, according to AP. The $20 coin features an engraving of William and Kate gazing lovingly into one another's eyes and an embedded sapphire-colored crystal that is reminiscent of Kate's 18-carat sapphire-and-diamond engagement ring. The coin will sell for about $105. The nickel-plated 25-cent piece has a colored photo reproduction of the royal couple based on a photograph taken at the 2008 wedding of a friend in Austria. It will sell for about $26. Both were unveiled Wednesday. The royal couple will visit Canada in June on their first official trip as a married couple. Queen Elizabeth II is the head of state in Canada, a member of the British Commonwealth of former colonies.
