South Africa's government announced Friday it will challenge the auctioning of dozens of artifacts belonging to the nation's anti-apartheid stalwart Nelson Mandela, saying the items are of historical significance and should remain in the country. The 75 artifacts belonging to Mandela, the country's first democratically elected president who spent 27 years in jail for his anti-apartheid struggle against the white minority government, are to go under the hammer on Feb. 22 in a deal between New York-based auctioneers Guernsey’s and Mandela's family, mainly his daughter Dr. Makaziwe Mandela.
