Ten days before their wedding, the Royal Canadian Mint has unveiled a special $20 silver commemorative coin.

Designed by Canadian artists Joel Kimmel, it features the Prince Harry and Meghan Markle as well as three Swarovski crystals and a border of roses and maple leaves.

The coin design was revealed at Toronto’s Centre for Addiction and Mental Health, in hour of Prince Harry’s advocacy for mental health issues.

He had toured CAMH last fall, 26 years after his late mother Diana, the former Princess of Wales, visited in 1991.

In his honour, the mint decided to also make a $25,000 donation to the CAMH Foundation.

The mint also made coins for Harry’s brother, Prince William, for his wedding to Kate Middleton in 2011.
