An ambigram is a form of typography, where a word is written in such a way that when it is rotated or mirrored, it is still legible.
When shown to others, they are often received with reactions of jaw-dropping and mind-blowing.
This ambigram coin does just that - on one side it reads 'Heads', and when turned around, those same letter-forms mirror to read 'Tails'. Not only is it a piece of art, but it can be used productively, for those moments when you have to make a choice between two options.
With a string of leather, you could also easily turn this into a necklace.
