North Korean coins 1959 with characters instead stars. Help to identify.

Hello everyone

I got these two North Korean coins but I could not find their KM# number. According to the catalog beside the number they should have one star, two stars or nothing. But these ones have a Korean character. I do not think that I have in my hands something "new" for the world of numismatic, so someone has some idea about them?
Thanks

I think it says "pattern," if I remember correctly.

I can't read Hangul, and that's probably something someone would expect from a Japanese kid.

I'm not sure they are patterns... I will check my WC tomorrow. If you can, please send pics of the obverses.

They are not in the catalogue that I can see...a date?

Sorry, 1959...first year of issue. Could it be first issue?
There were circulation restrictions w/o star for general circulation, 1 star issued to Communist countries, 2 stars issued to visitors from hard currency countries but no mention of characters!

I've check the WC and they are not mentionned...

This is the writing:

견본

The meaning is Specimen, so a collector issue.

I've found informations here: http://www.asia-coins.com/store/north-korea-coins

CiteerAlso of note are "specimen" coins, with no stars but intended for collectors. These, as well as occasional commemorative coins, are for collectors abroad, and are often particularly rare.

So they are a non-circulating mintage.

And they are on Numista!

Thank you very much for your help!

견 본 had the pronunciation "kyun bone" or "gyun bone" depending on your dialect. It means specimen. The South has put these words on all of their coins and notes and it is used to indicate a sample that has no legal tender. When the various central banks receive notes and coins back and forth that say "specimen" or similar wording, this is what South Korea sends out. I guess the North does as well.
