I have found that most foreign coins unless they are silver have little if any value on the collector market. Most of the dates I see are recent. I would prize them as examples of coinage from their respective country's and enjoy them!!
Great little collection! I have come to find that published book or web site prices on common coins means next to nothing.
Not real sure of any value, but at coincommunity.com forum, there are lots of people there from all over. I'm sure they can tell you what they are and how much they would be worth.
