Advertised as "the historical excavator that collapsed communism in Serbia," the bulldozer is being auctioned online with a starting price of EUR90,000 ($128,088), although it is "not in working condition."
The owner, known as Joe, drove the bulldozer during the Oct. 5 uprising against Milosevic's attempt to maintain his decade-long rule by preventing Serbia's pro-Western opposition from taking power after an election victory.
The bulldozer led columns of protesters in clearing the way to Belgrade's national assembly building where protesters broke in and clashed with Milosevic's special police.
The bulldozer also smashed through the glass walls of the offices of state-run television, allowing opposition supporters to stream in and occupy the building.
Hundreds of thousands stormed the government buildings during the uprising, forcing Milosevic to resign.
"The owner wanted to sell and we are helping him," Nenad Nikolic, who runs Limundo online auctioning told the Associated Press. "He determined the price."
The auction description for the bulldozer notes that "traces of these attacks are visible very clearly on the excavator itself, on the front, back and side" glass.
The bulldozer owner was not immediately available for comment. He has complained in past years of being forgotten by the post-Milosevic authorities and of living in poverty.
The choice of the city of Helsinki is not incidental as the capital of Finland had hosted US-Soviet negotiations on the limitation of nuclear stockpiles in 1969
