A Tokyo jeweler said Tuesday it will put on sale a pure gold replica of the facial mask and helmet worn by Darth Vader, a character in the Star Wars film series, for 154 million yen ($1.4 million).

The life-size representation, weighing around 15 kilograms, will commemorate the 40th anniversary of the release of "Star Wars," the first film in the sci-fi franchise.

Tanaka Kikinzoku Jewelry K.K. said the helemt and mask, 30 centimeters in height and 26.5 cm in width, will be put on sale on May 4, the date fans celebrate the series due to its iconic line, "May the Force be with you."

It will be displayed at the company's head office in the upscale Ginza shopping district beginning Wednesday.

The jeweler will also offer a commemorative plaque featuring three small oval coins made of pure gold and a replica Star Wars poster from the film's release 40 years ago. The plaque's suggested sale price is 1.22 million yen ($11,000).

The coins bear designs associated with the film series and the number "1977525," indicating May 25, 1977, the date of the first film's release. Tanaka Kikinzoku will sell only 77 copies of the plaque.
