Composition of coin and alloys in 2 euro coin

Rovšek, Barbara (avtor)

A few years ago, 14 year old students at the Slovenian physics competition were given the experimental task of measuring the composition of two alloys used in 2 euro coins. By performing some simple but as accurate as possible measurements of the density of the coin (and its parts) with simple measuring devices and applying some simple and justified assumptions, a surprisingly good estimate of the composition of the 2 euro coins was obtained. In this paper, we describe the density measurements performed to solve the experimental task and present the basic results of the competition.
