That Florin is one I'd have graded. It's a fairly commonly faked one. But an awesome fine, I am truly jealous.
It looks okay, has a beveled rim on the reverse - I haven't seen that on any fakes before and most real ones have it.
This one came today, another duit from one of the provinces of what is now called the Netherlands. Love that walking bird mint mark.
I had 1 of these once, but I had to sell it because of hard times and needed the money. very pretty gold coins.
Have this one coming from the Netherlands. Looks like it was just dug from the ground. Sellers photos. Would you give it an acetone bath or leave it as is?

I would say, tread cautiously. Try plain water first? You know as well as I do how the word "cleaning" is anathema to most of the folks here on CT. Real neat looking coin, silver is it? Yes, I see that now. I buy a lot of coins from the Netherlands. The past week or so, one of my favorite sellers from Utrecht was here on holiday and we got together a few times.
Thanks for the feedback coin-nut, I will try water then. Just soak and dab type rinsing. That's an amazing collection of VOC Duit's you have!
