You can still buy silver online using the Perth Mint Depository. They have unallocated and also physical allocated bars, dozens and dozens of 100oz + 1kg serial numbered bars: And you can have those bards delivered if you want. If you called Perth Mint and said you want to buy $1M worth of silver they'd bend over backwards to start up the machine for you right away. Just for kicks I went to ABC bullion and tried to buy 200 x 5kg bars ($4400ea) and it said the max limit was 99 bars. Then it told me the max shopping cart is $75,000 Again, if you called and said I want $1M worth you'd get it in short order I have no doubt.
