I have these 6 coins that I have no idea how to research them because I don't know what they are called. I have just started an interest in foreign coins-
well i think one of them is either chinese or japanese coin but im not for sure and i need to look up on the other coins.
From the image 40, you're looking at (clockwise from upper left) 1 - a two francs coin from the German occupation of France during WWII, 2 - a Japanese coin (10 yen I believe, although the image isn't perfect), 3 - a Greek coin (I believe it's 1 drachma). From image 44, the only one I can identify with any certainty is the coin at the bottom. It's also Greek. The one in the upper left hand corner looks like a euro coin, but I don't recognize the design.
The first one is from France, 2 Francs. The last could be from Greece. The pictures are very bad in quality, if you can upload better pictures maybe we can help you more. Also you can try to describe your coins.
Bottom picture, upper right, is indeed Japanese, but its a ¥100 coin, dated on the side not shown, under the large "100". It was the first cu-ni ¥100, and is either Y#82 (dated Showa 43-63 (1968-88), Y#98.1, dated Heisei Gan (1989), or Y#98.2, dated Heisei 2-present (1990-present). There have been several billion minted, and Krause lists them at $2.50-3.00 Unc. Edited to add: The second posting was made while I was typing this reply. The bottom picture is a ¥10 bronze, also dated on the side not shown, under a "10" within a wreath. With a milled edge it would be Y#73 (Showa 26-33 - 1951-58). With a plain edge it is either Y#73a (Showa 34-64 - 1959-89), Y#97.1 (Heisei Gan) or Y#97.2 (Heisei 2-present). According to Krause they are worth 45¢ to $35 Unc. (Only pre-1969 years are listed at more than $1.) With nine individual years of 1-billion+ mintage, there have been tens of billions produced.
2 Francs I knew the coin was 2 francs but the wondered what the "Travail Famille Patrie" meant- the coin feels like it is aluminum - dated 1943- wasn't sure if it was actually a real coin.
Vichy France, the area governed by Marshall Petain, often referred to as "Unoccupied France" during the first years of WW II, issued aluminum coins with that motto - "Work, Family, Country" - instead of the traditional French motto of "Liberte, Egalaite, Fraternite" ("Liberty, Equality, Brotherhood"). The scenes dealing with the Nazis in Vichy-controlled Casablanca in the movie of that name are accurately reflective of how unoccupied "Unoccupied France" really was.
Top picture, the bottom coin is greece. Probably 50 lepta by the size comparison to the others. definately 50 lepta from the obverse in the third picture - 1966, KM# 88
