"One asset is convertible to a 1oz 999 pure silver proof bullion coin, with a cold wallet attached containing 100 NEM. Worldwide, insured shipping included in price."
so the coin is worth more than the nem inside ? seems not very smart. i'd have bought some if coin was loaded with 100k nem for fun ("NEM will have a maximum of 4 000 000 000 coins")
my 2 cents 100NEM
Considering that the coins are selling for 100k NEM, I don't think it is reasonable to ask for silver/packaging/minting/shipping/insurance for free
