The Vancouver Sun reports in its Thursday edition that an upcoming Heffel art auction features works from a who's who of Canadian painters, including Tom Thomson, Lawren Harris and Emily Carr. The Sun's John Mackie writes, however, that the showstopper is a coin -- Haida artist James Hart's The Dance Screen (The Scream Too). It is a one-of-a-kind artwork commissioned by the Royal Canadian Mint, and is made from 10 kilograms of pure Canadian gold with a diameter of 18 centimetres. The face value of the coin is $100,000, but the artistic content is worth a lot more. It has a preauction estimate of $1.4-million to $1.8-million. The coin is based on Mr. Hart's cedar carving, The Dance Screen (The Scream Too), which was partly carved at the Vancouver Art Gallery and is now one of the signature works at the Audain Art Museum in Whistler. The original carving is huge -- 4.75 metres by 3.2 metres. The design was rejigged from rectangular to round for the coin, with Mr. Hart working with the mint's artists to get it perfect. Mr. Hart dropped by the Heffel Gallery on Granville Street on Wednesday with his wife Rosemary, the first time he has seen the coin in person (it was cast in Ottawa). "It looks pretty darn good," he said.
