Real or Not Korean 1 Whan.

Hi, i have two 1 whan coins. I don't know it's real or not. My friend just tell me its very rare, and say something about only 77 pieces around the world. At this moment i have only pictures. More info tomorrow.

These coins are definitely not real. The details are very poor and lumpy.

Hola Yo tengo esto que aun es mas raro por no decir falso, si alguien me sabe decir se lo agradecería, un saludo

 

Obverse is like this coin N#21043 and the reverse is like this coin  N#15833 .

Entonces es falsa o es un error? Esta bastante bien detallada 

Has to be a fake doesn't it? Is it silver? Is it 27g? Is it 38mm dia?

La compré así en un mercadillo porque me gustó el diseño está sin Abrir ni nada pegarse al imán no se pega por lo demás no sé nada
