Thank you very much Hippaforalkus!
I will cut correctly the picture of the first one and add it to the catalogue, although it is already very degraded and I don´t have Krause for this century, so it would be necessary to add additional information to the coin.
1st - 1.6 grams 20mm
2nd - 1.9 grams and aparently 20-22mm
It is strange, by the way, as catalogue says that 1/2 cent is 16mm/1.92grams and 1 cent 22mm/3.9grams . I don´t know if it lost weight or if it gained diameter anyway.
I already have a coin from the Dutch Republic... in a bad shape, I know... but I´m not an expert on cleaning, so I will keep as it.
