NEW YORK (AP) — A 1936 Nobel Peace Prize discovered at a South American pawn shop is heading to the auction block.

It's only the second Nobel Prize to come to auction. The medal will be sold March 29 in Baltimore by Stack's Bowers Galleries.

In today's market, the gold alone is worth over $9,000. As an object to collectors and world history, its value is much greater.

The 1936 Nobel Peace Prize recipient was Argentina's foreign minister, Carlos Saavedra Lamas. In the decades after his death, the award changed hands many times. An American collector obtained the piece some 20 years ago at a pawn shop.

The auction also includes the first Pulitzer Prize for Public Service to ever come to auction. It was presented to the now-defunct New York World-Telegram in 1932.
