The Royal Canadian Mint will issue a collector coin for the wedding of Prince William and Kate Middleton.

The coins will include an "eye-catching technological feature" that will be revealed closer to the April 29 wedding date, the mint said in a release.

"The Royal Canadian Mint has a long history of honouring royal milestones through finely crafted collector coins and the upcoming wedding of Prince William and Catherine Middleton is a priceless opportunity to celebrate Canada's pride in royal tradition," said mint president and CEO Ian E. Bennett.

Further details about the coin are not yet available. The federal government and Buckingham Palace must still approve the mint's design.

Despite the lack of details, a mint spokeswoman said the Crown corporation is confident the coin will be a top seller as royal wedding fever spreads across Canada.

The mint's announcement comes as Canada Post officials scramble to design a commemorative stamp after coming under fire for not planning to issue special postage.

"Historically and culturally, Canadians have a deep attachment to their royal heritage and our government is delighted that the Royal Canadian Mint is honouring their sentiments with coins," said Minister of State Rob Merrifield.

The U.K.'s Royal Mint has struck a £5 platinum coin to commemorate the nuptials. Only 200 of the platinum coins will be available, though sterling silver and gold-plated silver proof versions are to be widely distributed.

The Queen and the couple approved the design of the British coin, which shows William and Kate in profile.

The Falkland Islands, a self-governing British territory, has also issued a commemorative coin of the prince and his wife-to-be ahead of the wedding.

The Royal Canadian Mint's offering comes during a planned release of royal-themed coins leading up to the 60th anniversary of the Queen's reign in 2012. The two coins featuring William and Prince Harry were already scheduled to be released on March 15.
