The title DG Regina does appear on the 2002 10-cent coin.
In 2001, the Royal Canadian Mint temporarily changed the design of the 10-cent coin to celebrate the International Year of Volunteers. The Latin phrase, D.G. Regina, which is traditionally featured on all Canadian circulation coins, was omitted to accommodate the special 2001 commemorative coin whose design required additional art space. Commemorative circulation coins create important benefits by contributing to the overall success of the event being celebrated as well as generating additional seigniorage, or profit, for the government. In this case, the Year of Volunteer coin generated for the government approximately $9 million in seigniorage.
Both the traditional Bluenose design and the Latin phrase were returned to the coin in January 2002
