Okay, so a coin with wavy edges is pretty cool, but can you beat a triangular coin? Can you? No, I’m sorry, but I don’t think you can.
Oh, and yes, in case you think you’re mistaken, yes, that is a, ahem, a male reproductive organ peeping out on the $1 coin. Find me another coin with genitalia on it. You’ll be looking a long time, I imagine.
I’ve applied for a job at the Cook Islands mint, I reckon I can hold my own in their creative department. I’ll make the first 4D coin or something.
