How much is a 2001 Proof Krugerrand worth?

As the value of bullion Krugerrand coins is very much tied to the price of gold it is difficult to determine the price of a 2001 Proof Krugerrand. However, a good estimate for a 2001 Proof Krugerrand would be about 110% of the gold price.
On the 4 July 2016 a 2001 Ultra Cameo PF69 Proof Krugerrand was sold on ebay for US$ 1895 which would be around 145% of the gold price.
