The main device of the South Korean 5 Won coin (1966-1982) is the "Keobukseon," an armored warship of the Panokseon class of the Joseon Royal Navy, supposedly serving from 1500 A.D. to the early 1900s. It is featured in the recent film "The Admiral: Roaring Currents". I saw this movie on Netflix, and it was better than I had expected And then there's this medal, a commemorative piece made for the launching of a ship for a Korean shipping company. The Korean president's sixteen-year old daughter christened it at a shipyard in Spain in 1972. She's now the president of South Korea.
Almost every coin in this series has a ship on it and the ones that don't have an exploration theme. Sit back and enjoy.
Is that the 50% silver one? That one eluded me for so long, I remember when ever I got a 1968 in change I frantically looked everywhere for a magnet to test it and got let down when they stuck to the magnet. Until one day I found one dated 1968 in a box of dimes, when I put it against the magnet it didn't have the slightest attraction.
I really never checked . There was 2 minted for 68, one in philly and the other one in Ottawa . Reeding is different on either or . This ones from Ottawa ...
The easiest way to test it is to put it against a magnet, if it sticks then it is not silver, if it doesn't get attracted by the magnet then it is still.
If you are interesting in modern coins, Somalia has a big set of (unfortunately) colorized coins. But beautiful to look at. I'm just concerned about the longevity of colorized coins, if they were just plain I'd be interested in a set for myself. http://colnect.com/en/coins/list/country/2349-Somalia/series/216408-2015_-_Sailing_Ships
I also love coins with ships on them. Definitely no shortage of them throughout history. My favorites have an exploration (especially arctic) theme.
