Not error coins, but nice old pieces! I believe the first is from Gelderland in the Netherlands. I totally love that second one with the ship, but have never seen the design before! Where are the pictures of the other sides?
Lordmarcovan is right about the first coin. I don't have my references handy but I think it's a duit. Nice coin. These are relatively common issues, especially in this condition and would probably retail in the $5 +/- range. I'm not sure about the 2nd coin. It looks too crude to be an official issue, in my opinion. Just a guess, but it might be a jeton (counter piece). It looks like it could be 17th-18th century but I'm not sure. A pic of the other side might help
Maybe, or maybe just the wrong pictures, since we were discussing two old non-US coins, and your next set of pictures, instead of showing the other side of those, shows 3 US nickels (a common, damaged Buffalo nickel, a modern Jefferson worth five cents as pocket change, and another Buffalo nickel)?
