The prestigious prize was awarded to Tunisia's National Dialogue Quartet on October 9th for its work in building the only democracy that emerged from the Arab Spring.
The Nobel medal is awarded to individuals or to a group.
This year, it went to the quartet, which will receive the official solid gold medal.
But the four separate groups that make up the quartet — the Tunisian General Labour Union (UGTT), the Tunisian Confederation of Industry, Trade and Handicrafts (UTICA), the Tunisian Human Rights League and the Tunisian Order of Lawyers — all want to each have their own medals as well.
At the Tunisians' request, “four [more] medals will be struck,” Nobel Institute director Olav Njolstad told AFP, ahead of the award ceremony in Oslo on December 10th.
It is not yet known where the fifth medal — the one awarded to the quartet collectively — will end up.
The Nobel panel can mint up to three replica medals in gold-plated bronze for laureates, but the Tunisians wanted their replicas in solid gold, like the original.
“They are paying the difference in price that this involves,” Njolstad said, without giving details. “The price of gold varies from day to day.”
Another Nobel innovation this year is that the official medal will be labelled “Fairmined,” guaranteeing that the 150 grams (5.3 ounces) of precious metal that goes into each award is ethically mined.
Formed in 2013 when the process of democratisation was in danger of collapsing in Tunisia because of widespread social unrest, the quartet established an alternative, peaceful political process as Tunisia was on the brink of civil war, the committee said.
