Puzzled about this coin “Willem van Bronkhurst 1556?”

Can you help find some information about this coin found a couple of weeks ago in my garden ?

Awesome find.

you could try to clean it with
A small pot, cover the inside with aluminium sheet.
place the coin inside.
fill the coin with a layer of pure baking soda (Kaisernatron).
pour it with boiling water to cover it fully.
leave it for around 20-30 seconds.
Repeat the pricess if needed.

use this method only for high silver content pieces.

could it be this one? https://www.acsearch.info/search.html?id=2766672
When asking for an identification, please always provide the weight and diameter.

One side of the coin matches nicely with this. Not so sure about the other side. Perhaps this will lead to your specific coin.

The method I mentioned above should do no harm to a Taler coin

Hi thanks for the information!
tried it on a couple of the more Common looking coins. One came up nicely but the other got a copper sheen to it ! Is that harming the coin?
cheers Greig

All where high silver content coins?
Also only one coin at a time and after finishing with a coin if there was a lot of crud its best to change the aluminium foil before starting with the second.
