numismatics - a hobby for the older generations or sustainable profit from collecting coins over time?

Can coin collecting become a smart investment?

Yes! We developed numindex to dispel the myth, that collecting coins (numismatics) is a hobby for elderly and wealthy people with plenty of time & know-how

We believe that anyone can start just now and create a profitable coin collection in no time

We aim to help individuals to grow their sustainable alternative investment in coins

We have reinvented coins collecting –

making it fit our digital times


the numismatic coin market index (numindex) is a group of 30 coins, which circulated across europe
all 30 coins within numindex have been precisely selected by european numismatists to ensure them being relevant, affordable and profitable. numindex shows price development of the mentioned set starting from 2018 up till today. it enables a comparison of all coin prices from the index and to track the performance of the collection over time. General rules used for calculating numindex and details of each coin (including visuals) are available under coins.

numindex value is expressed in points. to learn how we calculate numindex, read the white paper.
