What is just the second Nobel Peace Prize medal to be sold at auction will go under the gavel later this month at the Baltimore Convention Center.

Lot #2029 at the Whitman Expo's spring auction of coins and collectibles will be the 1936 gold medal awarded to Argentina's former foreign minister, Carlos Saavedra Lamas. He received what arguably is the world's most prestigious prize for his role in negotiating the end of a war between Bolivia and Paraguay.

The auction will be held March 27-30.

According to a notice on the website of the California-based auction house Stack's Bowers, this is only the second time that the Nobel Peace Prize has been sold at auction.

Though Nobels in other disciplines have been sold to benefit charities and for other reasons, only the peace prize won in 1903 by Sir William Randal Cremer previously has gone up for sale to the highest bidder, the Stack's Bowers website said.

Lamas' 23-karat medal weighs more than 222 grams. The gold alone is worth $9,000, according to the website.

After Lamas — the first Latin American to be awarded the Nobel — died in 1959, his medal eventually was purchased by a series of American collectors. Stack's Bowers, which specializes in the auctions of valuable coins, is handling the sale for the estate of the medal's most recent owner.
