This gave me an idea for a gimmick die. Transparent die filled with dark liquid. The exterior of the die has the usual numbers in white lettering. Inside the die, there is a smaller cork die that rises like a magic 8ball. It’s 2d(x) in 1. Interesting for tension building, if nothing else.

A standard US nickel, yes. I prefer better odds than that… [Thick Nickels](https://thick-coins.net/)

It has only 1 corner, and 2 surfaces, making it 2 sided. The 2 sides just happen to be curved

> 1 corner, and 2 surfaces Doesn't it have 0 corners, 1 edge, and 2 surfaces (faces)?

That extremely rare, almost-never chance of landing on the edge is exactly what I would program into a game if I made one, instead of exactly 50% odds.

Or you know, a coin.

Looks 4-sided to me

Not if it's a [thnickel](https://thick-coins.net/).

The picture is of a d4. Dice are measured counting the flats (and therefore possible number of different results) not mathematically defined "sides".

One of my overdue projects is to disassemble a magic 8 ball, remove the dice from it and make a digital magic 8 ball. I plan to bequeath the removed “dice” to a DM I know.
