Czech Republic 20 koruna 2012 - New material
New circulating sub-type:
I've just been told about a new golden colour alloy used for this Czech circulating type. The coin still has a magnetic core, but the cover alloy is different now, so that it's conservation will be better over the years.
Further details and exact composition data are still awaited.
