Numista is not the place for buying or selling coins.

At least two 1561 mariengroschen are being offered for sale by Munzenhandel A.J. Koci and Munzenhandlung Manfred Olding. Koci tends to have prices on higher side. It is against the rules to post links to sales and you will have to find them themselves, if you want.
