One of the coins is from the Shōwa era... Will you find it ?

The second coin (Israel) seems to be not a real coin. It's not on Numista, it's not in Krause, there is no date on it.
The design resembles the old design so I don't think the coin is so new it's not in Krause yet.
I've never seen this coin yet.
I don't understand your last post. Why those question marks? In the previous posts PetrusAscanus and eazy.dog gave the right answers, including the links to the Numista catalog.
So:
#1: Taiwan, 1 yuan 1975 (not from "around" 1975 but from 1975)
#2: Israel, peace token
#3: Japan, 1 sen 1937
in the reply, there was nothing as far as the denomination of the Japanese coin and there had been a question mark in the reply about the first coin which was the first reply

For every of those three coins there was a reply with a link to the page coin for every specific coin. You just have to click on these links to get every information, including the denomination.
So I assume you missed those links for some reason?
