Euro coins also raised about Poongsan's presence on the vetted list of coin blank suppliers of the European Commission's Mint Directors Working Group. However, the Commission claimed responsibility on this issue lies with the member states of the Union. Euro coins There are eight euro coin denominations, ranging from one cent to two euros (the euro is divided into a hundred cents). The coins first came into use in 2002. They have a common reverse, portraying a map of Europe, but each country in the eurozone has its own design on the obverse, which means that each coin has a variety of
Coin problem 1. There is an explicit formula for the Frobenius number when there are only two different coin denominations, "x" and "y" : "xy" − "x" − "y". If the number of coin denominations is three or more, no explicit formula is known; but, for any fixed number of coin denominations, there is an algorithm computing the Frobenius number in polynomial time (in the logarithms of the coin denominations forming an input). No known algorithm is polynomial time in the "number" of coin denominations, and the general problem, where the number of coin denominations may be as large as desired, is
