U.S. Sen. Kay Hagan wants the U.S. Treasury to create a commemorative coin to honor the 50th anniversary of the Woolworth’s civil rights sit-ins in Greensboro.

On Feb. 1, 1960, four students from N.C. A&T University sat at the whites-only lunch counter in downtown Greensboro and refused to leave, Barb Barrett reports. The protest sparked a movement throughout the South.

Hagan, a Democrat from Greensboro, plans to introduce legislation ordering the treasury to mint 1,000 U.S. $1 coins to commemorate the anniversary of the sit-ins. The bill would be deficit-neutral, her office said, and would cost the public $11 per coin.

The design would be selected by the U.S. Secretary of the Treasury, in consultation with the International Civil Rights Center and Museum, which is being built at the site of the Woolworth’s counter in Greensboro.

U.S. Rep. Brad Miller, a Raleigh Democrat, will take the lead in sponsoring the bill in the House. Miller’s district, which stretches into parts of Greensboro, includes the museum site.
