Wall Street sign sells for $133,000

A vintage sign that once marked an intersection near the New York Stock Exchange has sold for $US116,500 ($A133,021) at auction.

Christie's said the enamel "Broad St" and "Wall St" sign was bought by an unidentified phone bidder.

The auctioneer had estimated its value at $US60,000 ($A68,509) to $US80,000 ($A91,345) before the sale.

The sign stood in front of the former headquarters of J P Morgan & Co in New York.

The intersection was the scene of a 1920 Wall Street bombing that killed 38 people and injured hundreds. Shrapnel scarred the sign.

Christie's says the sign went up in the late 19th century and came down sometime after the bombing.

It was recently shown at the Museum of American Finance in New York.
