I noticed an error in the Numista catalogue: what can I do?

The coin, banknote and exonumia catalogues on Numista are collaborative catalogues, built over the years by the users of Numista. We encourage everyone to correct any error, mistake or typo found in the catalogue.

 

If you notice an error on a page of the catalogue, click the link “Modify or add data on this page” at the bottom of the page, in the section “Contribute to the catalogue”. 

This link opens a form containing all the information on the page. If not done yet, you will need to sign in or create a free account on Numista. In the form, you can correct the error your noticed. Please respect the Guidelines of the Numista catalogue and indicate your sources in the last field of the form; then submit with the button “Modify data”. 

Your correction will be verified by the referee in charge of that part of the catalogue and published.
