To the person from the Ukraine that was interested in buying a few (I can't find your message/post):
I don't think I can send silver to the Ukraine.
PROHIBITIONS:
Coins; banknotes; currency; securities of any kind payable to bearer; traveler's checks; platinum, gold, and silver (manufactured or not); precious stones; jewelry; and other valuable articles are prohibited.
So many countries say this, but I have not had an issue sending Casascius Coins (including silver) anywhere.
I describe it as a "medallion".
If I ship them in capsules within DVD mailers, well, I have never had one go missing or ever heard anyone had a problem.
