Thanks for posting! I'd put the grades on it as I can see it on the pictures. Please know that I am not a professional and that I might come up with different grades when having the coins in hand. I'd use European grading on these coins as I am European and the coins are as well. Americans add a number between 1 and 70 to the grades to be even more specific.
Anyway, top row, left to right:
Fine, Very good (but cleaned?), Fine (but cleaned?)
Bottom row, left to right:
Fine, Very good (but cleaned?), Very Fine
I really love to see these coins. I have lived in The Netherlands for many years and I am still trying to build up a Dutch type set, although it is quite difficult to find any coins where I am situated now. Especially the VOC coins (ducatons, like these)and the 3 gulden coins are difficult and really require a trip to a foreign country...
Anyway, I can also recommend, in addition to this site, to look here and search fro Netherlands and Netherlands East Indies to get more information on your coins:
