Rare PAMP set "Legendary gold rushes of the world"

Hi guys,

I came across this box containing 6 x 2.5 grams of gold + 1 gram of a real gold nugget (see the picture).
I'm not sure about how rare or valuable this set could be. The mintage is only 5000 though.

Any ideas of a potential resale value on this one??

Thanks!
