Store of Value

A recognized form of exchange can be a form of money or currency, a commodity like gold, or financial capital. To act as a store of value, these forms must be able to be saved and retrieved at a later time, and be predictably useful when retrieved.

Storage of value is one of several distinct functions of money. The other functions are the standard of deferred payment, which requires acceptability to parties owed a debt, and the unit of account, which requires fungibility so accounts in any amount can be readily settled. It is also distinct from the medium of exchange function which requires durability when used in trade and to minimize fraud opportunities.

1. With money being a storage of value was the start of monetary inflation cycles where the under and over abundance of market goods can lead to price instability.

2. Common alternatives that act as stores of value are:

* real estate - actual deeds in protectible land
* gold - once the basis of the gold standard
* silver - once the basis of the silver standard
* precious stones, and precious metals
* collectibles, e.g. original art by a famous artist or antiques
* livestock (see African currency)
* stock

While these items may be inconvenient to trade daily or store, and may vary in value quite significantly, they rarely or never lose all value. This is the point of any store of value, to impose a natural risk management simply due to inherent stable demand for the underlying asset. It need not be a capital asset at all, merely have economic value that is not known to disappear even in the worst situation. In principle, this could be true of any industrial commodity, but gold and precious metals are generally favored because of their demand and rarity in nature, which reduces the risk of devaluation associated with increased production and supply.

Anti-counterfeiting measures

Traditionally, anti-counterfeiting measures involved including fine detail with raised intaglio printing on bills which would allow non-experts to easily spot forgeries. On coins, milled or reeded (marked with parallel grooves) edges are used to show that none of the valuable metal has been scraped off.

This detects the shaving or clipping (paring off) of the rim of the coin. However, it does not detect sweating, or shaking coins in a bag and collecting the resulting dust. Since this technique removes a smaller amount, it is primarily used on the most valuable coins, such as gold.
In early paper money in Colonial North America, one creative means of deterring counterfeiters was to print the impression of a leaf in the bill. Since the patterns found in a leaf were unique and complex, they were nearly impossible to reproduce.

In the late twentieth century advances in computer and photocopy technology made it possible for people without sophisticated training to easily copy currency. In response, national engraving bureaus began to include new more sophisticated anti-counterfeiting systems such as holograms, multi-colored bills, embedded devices such as strips, microprinting and inks whose colors changed depending on the angle of the light, and the use of design features such as the "EURion constellation" which disables modern photocopiers. Software programs such as Adobe Photoshop have been modified by their manufacturers to obstruct manipulation of scanned images of banknotes.
