Not how I would spend the $$, but still a worthy endeavor.. https://www.youtube.com/watch?v=YH22UR5nTVY [youtube]http://www.youtube.com/watch?v=YH22UR5nTVY[/youtube]
He's a US stacker. Boxes came from Apmex.. http://www.apmex.com/product/85257/new-premium-6-coin-set-box-silver-lunar-series-ii Those fit the 1/2, 1, 2, 5, 10 & kilo. There's another box at Apmex that he used for the 1/2 kilo. Supposed to be a kilo box, but same diameter as 1/2kg. His channel recently chronicled his adventures in obtaining a lot of them, one by one. Seems like a lot of hunting went into it. Picked 'em up from the US, AUS & Europe. Cool idea, cool collection. Probably not many out there, I'd imagine.. Though I suppose over time, more would be put together.
Provident is selling the 10 kilo goat by the way. It actually has a huge premium considering the amount of weight it is.
