thanks for answering, I consider to buy some newer coin with a good potential.
the problem is just you have nothing in real. Why not making these coins able to print out,
and exchange like real money? much easier for customer. if you put an QR code on it,
to check if it is ok.

btw at this moment silver is very attractive, what do you think?
I am thinking to get some fine silver, and I got something in my hands if electricy is down
and bank money is not available (you never know, with the financial crisis)
