WASHINGTON — A coin commemorating the 225th anniversary of the U.S. Marshals Service would be minted in 2014 under legislation nearing final approval in Congress.

A full court press by Sens. Mark Pryor, D-Ark., and John Boozman, R-Ark., to round up co-sponsors succeeded Friday in reaching the 67th needed to bring the bill to a vote. They added 37 co-sponsors this week, bringing the total number of supporters to 68.

Sales of the coins could provide up to $5 million for the planned U.S. Marshals Museum in Fort Smith.

The senators were awaiting word Friday evening as to whether any colleague objected to passing the bill by unanimous consent. If not, Senate leaders hoped to forward it as soon as possible to President Barack Obama for his signature. Action could come late Friday or Saturday.

Congress has established unique rules for approving commemorative coins. Sponsors must sign on at least two-thirds of their chamber before a floor vote can be cast. Congress is also limited to approving only two commemorative coins in any year, a reflection of the U.S. Mint’s ability to produce such coins.

The House voted Thursday, 412-1, in favor of the proposal after Reps. Steve Womack, R-Rogers, and Mike Ross, D-Prescott, had secured more than 300 co-sponsors.

Jim Dunn, executive director of the planned museum, was in the public gallery Thursday to watch the House vote.

First and foremost, the coin would honor more than 240 marshals who have died in the line of duty, Dunn said. Also, the minted coin could provide up to $5 million to the museum to help preserve the history and artifacts of the nation’s oldest law enforcement agency.

“It will help us educate the American people about what all the marshals service had done for 225 years,” Dunn said on Thursday.
