Generally the easiest bullion gold products to transport internationally are government issued 24k gold coins with legal tender face values. Many governments (Canada and Singapore for example) tax 22k gold coins so if you are thinking about moving your gold bullion abroad, I suggest steering clear of 22k Gold Eagle and Gold Krugerrand coins.
If you are going to use 24k gold bars I suggest buying government issued bars. Even though they may not have legal tender face values, if the border guard sees a government stamping on it they are less likely to give you trouble.
For silver, you’ll do best for international shipment if you choose .999 fine sovereign silver coins with legal tender face values. Throughout Europe, silver is taxed heavily:
For international shipping of your own bullion the best 3rd party options are G4S, Via Mat, Brink’s, etc.
If you are physically carrying a lot of bullion yourself across a border, I suggest asking for a private screening so as to not make a scene at the airport or border crossing.
One other note, when you are crossing borders you may be presented with a customs declaration form to document what you are traveling with (the U.S.A. wants you to declare if you have $10,000 or more in cash, cash equivalents, gold, silver, bonds, stock certificates, etc.).
Some people may try and play it cute by only reporting the fiat legal tender face values of the coins that they are transporting. I suggest that is foolish, for you may end up provoking a border guard who knows the true value of the coins and potentially causing more attention than is necessary.
