Homeless people were among the hundreds of people who lined up outside the Denver mint Tuesday to get a freshly minted 24-karat gold Kennedy half dollar.
The lines stretched for several blocks and coin dealers paid stand-ins because the coins were only one per person.
The Denver Mint wouldn't say whether or not the practice is allowed.
The coins sold for $1,240 apiece. They commemorate the 50th anniversary of the Kennedy half dollar.
Five hundred of the proof sets were on sale in Denver Tuesday. Another 100 go on sale every day through Friday.
The coins also went on sale at U.S. Mints in Philadelphia and Washington, D.C.
