OK, another Fishrrman off-the-wall prediction:
Everyone in this thread is missing an important reality (from the future that I see coming).
Once the communists gain full control here -- after they have moved beyond the "democrat-communist" transitional period -- they're going to declare private ownership of gold AND silver illegal.
Citizens will be required to turn it in voluntarily or be subject to having their homes raided. Compensation, at best, will be the new "blue bucks" that are introduced to replace the current green dollars -- at a rate of 100 or maybe 200 green for one blue in return.
At worst, there will be no compensation at all.
I predict the silver black market may survive, with "low denomination" old "junk silver" coins being a medium of exchange.
