In modern times, any national currency that is expected to retain its value (and even appreciate in value), and is readily acceptable for most international transactions.

COST: Best referred to as opportunity cost, this is the highest valued alternative foregone in the pursuit of an activity. This is a hallmark of anything dealing with economics -- or life for that matter -- because any action that you take prevents you from doing something else. The value expressed in terms of satisfaction of the foregone activity is your opportunity cost. Because there are usually several alternatives that aren't pursued, opportunity cost is the highest-valued one. An opportunity cost is sometimes compensated with some form of payment, like a wage. However, the existence of an opportunity cost is independent of any actual cash outlay.

SIGNALLING

When confronted by asymmetric information, the use of small bits of information, or indicators, that suggest more comprehensive information. Signalling is used by those with more information to reduce the cost of informing those with less information. It is commonly used in markets with adverse selection. Methods of signalling include advertising, brand names, and warranties. A related method is screening.
