Inherited many coins and of them all I can’t figure these out because I’m not sure how to type it in anywhere haha. Thanks in advance
There's a book of world coins that has a table where you can identify the country by comparing the characters, from there you can scroll to the country, find the coin year and approximate value.
The small aluminum coin is a Japan 5 Sen dated 1942. https://en.numista.com/catalogue/pieces9225.html
I can't help because I don't collect foreign coins but welcome to CT. We do have a number of members that do so best wishes.
