I can't see this as a coin

As I strolled through the 'Latest coins' section I came across this 'object', supposedly a coin.
https://en.numista.com/catalogue/pieces193994.html
But if the dimentions on the page are correct this object should have a thickness shy of 0.5 µm!

For comparison a 6µm carbon filament against a 50µm hair

I guess it's just a gilded piece of paper and/or plastic. But if this is a coin the banknote crowd can rejoice and but all the rectengular paper coin on Numista right now and don't have to wait for Notista.

Cook Islands, what else to say

That weight of 0.1g is unrealistic.

Citeer: "Cerulean"​That weight of 0.1g is unrealistic.

​I agree, though I found plenty of online descriptions giving the same figure.
(Plus one claiming 0.3 grams, and one claiming 5 grams and 0.045 mm thickness for a different banknote-shaped Cook Islands type.)

Best I can tell, there might, in principle, actually be just 0.1 grams of actual gold there (in a very thin foil, which by itself is not too implausible), but it is then laminated and/or covered with paint, and the full object weighs more than 0.1 grams.

More likely, someone mistook the thickness as the weight.

Two layers of gold leaf per side could account for the gold (gold leaf being around 0.1µm thick) but what characteristics woud make this a coin?
There are many trashy mint product with silly shapes like countries cubes or even bottle caps but at least they were 'minted', and most often for tokens that aren't out of metal they are roughly 'coin' shaped.
It is clearly no more than any other gimicky gold note.

I consider it a joke and it should be deleted from the database.

Unfortunately, the bottom line for the catalog wasn't clearly drawn in the past and now we have thousands of this 'products' in the database.
