The numismatic index numindex transparently shows how the prices of selected European coins change over time. In the style of a stock index, it was designed for collectors who consider their collection an investment.
On 22 March 2023, the numindex was at 1582.57 points, while it had been at 1358.37 points at the beginning of the year.
The numindex is based on the data of 30 European coins, which are suggested as starting points for a new collection by the index’ initiators. The development of the index over the past years and the prices of the individual coins can be found on the website of numindex.
In this article, Michael Zagorowski explains more about the background of numindex.
