Looking at the work of Russian artist Roman Booteen, it’s easy to see why people consider him a master at hand-engraving coins, but what most people don’t know is that many of his masterpieces also feature jaw-dropping mechanical surprises.
One of Roman’s latest creations is a prime example of why people are so blown away by his skill. It’s a silver dollar featuring the detailed carving of a knight and woman looking at a indentation on a wall. In a video posted on his Instagram, the artist reveals that the knight’s sword is actually removable and can be inserted into a little notch on the edge of the coin to slide open the wall indent and reveal a golden chalice. And this is just one of the cool things that Roman Booteen has made over the years.
