Coin thickness(Need a referee of Myanmar, ancient).

So I was surfing through and I found that this coin has a thickness of 0.2 mm. Isn't that just too thin? I have the coin and I checked; I found it was 2mm, not 0.2. Did someone make a mistake?

N#157519

Probably a mistake.

Probably a mistake. Make a CR to have it modified, try to show your caliper with the thickness of the coin in an image.

I am so sorry for not replying sooner. Thank you very much!
