These are the coin jigsaw puzzles carefully cut and crafted by the folks at Coin Cut Art from real coins. Those are some tiny puzzle pieces! Prices range from $15 - $225 depending on the coin used (you can even send your own), and, just like your ex-boyfriends penis, are probably best handled with tweezers. High-five!
Keep going for several more examples.
Thanks to Dab, who just did the same thing to a dollar bill and now the cashier at 7-11 is refusing to accept it in trade for a jalapeno and cream cheese taquito.
