New South Korean coin not listed here yet

Been working on some 'unidentified' coins today and found 1 that wasn't on this site yet.

It's a South Korean 5 won called Iron Clad Turtle boat and is made from brass.

In the world catalog it has KM5a and the following years exist :
1970-1971-1972-1977-1978-1979-1980-1981-1982-1982proof

Here are the scans




I didn't put it on the site yet, cause it says Korea and this 1 is from South Korea.

If you need more info pls mail me.

I will wait untill the site owner decides to put it up on the site for now.

Oops I must be dreaming....

Just found out that there is a North and South Korea on the site. sorry all.

Blame the books I'm looking in for all day lol.

This is the coin you're talking about:
