Adopt a coin

By adopting a coin or medal you are supporting the documentation of our holdings and their publication in our Online Catalogue. You may select any number of objects for 25 euros each from those online, see under ‘Holdings’/ ‘Vault’. You may also adopt coins, which have not yet been documented online. In this case, please do contact us to discuss your area of interest.

For German residents, your donation is tax-deductible. For amounts up to 200 euros a transfer voucher will be accepted by the Tax and Revenue Office. For larger donations, the HHU will be pleased to issue a receipt.

If you would like, your name will be added to the object entry in the Online Catalogue.


Your donation is used exclusively for the ongoing documentation of our holdings. Each individual donation covers the costs of scientific documentation of one object. The coin adopted will be processed into our Online Catalogue by (undergraduate and graduate) student numismatists supervised by the institute's staff.

Thus by adopting a coin, you help us to provide more information on an ever growing number of objects from our holdings through the Online Catalogue. In addition, you would also be encouraging future generations of numismatists currently in training by providing an opportunity to deepen their studies of particular objects in our collection and to earn a little money as well.

Don't hesitate to contact us.
