20 cents 2018, km1411, variants or weak strike?

N#6373

I have this coin, how would you estimate it?  As a variant or an error?

Thanks for your comments

Have you found one or many?

To be honest, I don't look for them, so I only have one, that's why I'm in doubt about variant or not.

In that case not a variant. Weak strike or filled die.  I looked on Ucoin and couldn't find any like it.

Thanks, that's what I thought as well.
