A trunk full of black money?

Eventually by various means and devices the victim will be persuaded that the trunk contains a large sum of cash, which cannot be transferred in any other form (bonds, cheques, etc.) for some reason. In addition, the bills have been dyed black or some other color in order to avoid detection or seizure by customs officials. The victim is assured that the chemical needed for removing the dye is also in the trunk.

The victim may have already paid some money to pay fees and taxes, and he may now be invited to pay the shipping expenses of the trunk to his home country. Whether these are paid or not, the trunk will not be shipped and further sums will be demanded on various pretexts, such as taxes, security company fees, money transfer fees, legalization fees, export permissions, etc.
