The CG 166823 shows only one hole and was submitted on 2016-07-17.
Although we are glad that we now have the picture of the obverse we can not delete the name of the contributor that is listed.
So I searched for a Belgium solution, we are used dealing with different opinions.
Hope you like it, it's effective as of tomorrow.

BTW: size matters so if you, or Mickaël, can provide us with that it would be super!

Hope this helps?

Jo from Belgium.
