Canadian Banknotes is 100% right on this subject.
About 6 months ago, I took into possession 100 oz via 10oz NTR Metals bars. These were being sold on kijiji and at just below spot so I grabbed all 10.
I immediately took them to my local bullion dealer where I turned the 10NTR Metal bars into 10 JM Bars. I paid $1 an ounce to do so.
Fast forward to today, these 10 NTR bars are still there.
