ID help - Japan, Middle East, Germany

Here are four coins I recently picked up that I can't identify. Help on the country, denomination and dates would be greatly appreciated. In this lot I have two from Japan and one from a Muslim country.

This one I'm guessing is Prussia, but I don't know for sure.

 

1) Taiwan - 1 Yuan - 1960 - Yr.49 - KM#536

2) Japan - 10 Sen - 1922 - Yr.11 - KM#49

3) Muscat & Oman - 3 Baisa - 1958/1959 - Yr.1378,AH - KM#30

 

Thanks, that was quick. Muscat & Oman is a new one for me. I didn't have any from there before.

 

I carn't figure out what state that is. I don't think it's Prussia. Their shilling coinage only goes up to the mid 1700's. I could be wrong though.

Thanks for the help.
