Online sales had begun just after midnight, and officials said they were gone by 11:15 a.m. Monday.The coins depict the official sesquicentennial logo on one side and a detailed engraving of the state seal on the other. They sold for $49 each.The West Virginia Sesquicentennial Commission continues to offer a brass version of the coin, set into a keychain and available online for $8.West Virginia split from Virginia during the Civil War. Activities commemorating the state's birth are leading up to a major celebration in Charleston that runs from June 20 through the June 23 anniversary of statehood. Those events include concerts and parades as well as a 3-D movie and three nights of fireworks hosted at the state Capitol. The state also issued a commemorative coin in 1963, when it turned 100. Those have become collector's items. First lady Joanne Jaeger Tomblin wears one that has been fashioned as a pendant for a necklace. Kay Goodwin, the governor's Education and the Arts secretary and sesquicentennial commission chairwoman, also has one passed down from her mother.
