(Bloomberg) -- A Berlin court convicted three men for stealing a 100-kilogram (220-pound), solid-gold coin worth $4 million from a museum in a heist that could have been out of a Hollywood movie.

Two men, 23 and 21 years old, were sentenced to four and a half years. The third, a 21-year-old security guard, must serve three years and four months. A fourth accused was acquitted, German newswire dpa reported.

They were tried under rules for juveniles which reduces the prison terms that could be imposed. Prosecutors had asked for five to seven years. The defense sought acquittals.

Three years ago the coin -- which carries Queen Elizabeth II’s imprint and is called the “Big Maple Leaf” -- was stolen from its case in Berlin’s Bode Museum. The perpetrators were able to circumvent the alarm system.

The coin was as big as a car tire and is still missing. Police assume it was cut into pieces and sold.

It was issued by the Royal Canadian Mint in 2007 and was the biggest gold coin at the time. It had been on display in the museum since 2010, on loan from a private owner.
