Because nowadays nearly everything is for sale on the internet, try searching for old Dutch, Spanish, French (etc) coins from the 1600s/1700s. Back in the pre-internet era, I saw a huge book titled something like "Coins of the World" or the "World Book of Coins." (Similar to the "Red Book" on US coin values.) It covered coins from all over the world, dating from the present back into (at least) the beginning of the Colonial Era. I'm sure there's no equivalent viewable for free on the internet, but some coin-dealer websites might have a section on Colonial Era European coins.
