Naturhistorisk museum is nice, and that remains me that I have not been at the NM for a long time. Should definitively go there soon. The white part is just some plastic encapsulating the coins, as I have not removed it from the box. Should probably have done that for better pics and for a more genuine feeling of the coins, but I do not have any gloves yet to handle it. Fingerprints (with biological residues) destroy coins (perhaps not so much gold) over time.
