The Bretton Woods Conference aimed to iron out wild exchange rate fluctuations
following the abandonment of the gold standard.
The factors include: the decline of sterling, the United States’ involvement in the Vietnam
War, especially the rise in barrel prices.

combined with the inexperience of the European Central Bank in dealing with the international market, has caused the decline of the value of the euro since its launch. The ECB is relying on an assortment of security measures to protect the currency, from
the look and feel of the paper to holograms and incandescent strips.
Coins are round, but have differences in composition, weight, thickness, and milling to
ensure that the blind can easily distinguish between them. Ex. 3
