A brief annotation
On 14.10.2012 Riga Technical University (former Riga Polytechnic Institute – RPI) celebrated its 150th Anniversary.
Many outstanding researchers were educated and worked there, among them chemist Vilhelms Ostvalds (the only Nobel Prize winning chemist of Baltic origin) and Pauls Valdens (chemist and rector of the RPI, seven-time Nobel Prize nominee).
The coin has been designed as a small yet practically employable tool, which enables the measurements of size, direction and source of origin. Modern coinage technologies have been of particular importance for the emergence of this coin.
