Looking for certificates for coins

Hi All !

I'm looking for certificates for 2 silver coins of Belarus :

20 Roubles Amerigo Vespucci : https://en.numista.com/catalogue/pieces23239.html
20 Roubles Krusenstern : https://en.numista.com/catalogue/pieces36294.html

I can offer in exchange for the coins from my swap list.

Thanks !

Best regards,
Andrey.

I need only the certificate for 20 Roubles "Krusenstern". Another certificate I have found.

COA certificates to me are worthless, they are so easily made at home.

All you need to do is find one on google and then print it out onto white card.
