also here is a grey area question. Say silver and gold do hold value in the SHTF situation. Do you think there will be a way to tell purity?
Would it be smarter to buy a **** load of low percentage gold as you can get it easier right now and there may not be able to tell the difference in the future.
You can get a **** load of fake chinese silver for next to nothing and without acid tests alot of them can be hard to spot.
If you plan to take gold or silver in barter it would be a smart move now to buy some testing kits - Currently they are cheap and readily available
Someone years ago tried to sell me some 99.9 bars that were 10kt at best so that trick has been around for a while
