Weight - Diameter [solved]

I have no doubt that such a drawing can be placed on a 16mm coin. I doubt that the size of such a coin is 0.03 grams. I assume it should weigh 0.3 grams?

0.15 grams.

Thank you so much for your attention and clarification. I thought only the one who published the information about the coin could fix it. 
How can I send a change request to fix this. Please provide a link?

I've already registered modification request to update it. Pending for referee to review it.

Every coin page has edit icon on top right or “Modify or add data on this page” link on the buttom.

I am grateful to you. Thank you.
