Sir, what who describe looks more like a piece of paper than a coin.

Ideal coins are inflexible.

Ok, so a thin layer of adamantium is an ideal coin, but not a tiny disk of metallic alloy engraved with pictures, texts and values !

Well, an ideal cow is a perfect sphere, so.

And a very very funny joke, at that

So would you say I solved the case?

I think Skua might be right, d2?

How can it be a D2, I can literally see 3 sides with my very eyes.

It can be viewed as two interlocking 'c' shapes, so it *could* be dressed as a d4, with a different value at each end of the 'c.' Alternatively, each 'c' can be considered a single side, making it a d2. Since we already have d4 well represented by the 4-sided triangle, aka tetrahedron d4, this design strikes me as more valuable as a d2

Why not throw a coin at that point?
