CoinSilver Kilo - Penrose Triangle Bar

Apart from regular circulating coinage, Slovakia has mints that produce bullion which is not legal tender and is targeted at investors and not at coin collectors - such as this one.

This silver bar made by the Pressburg Mint depicts the Penrose Triangle. Also known as the Penrose tribar, the impossible tribar, or the impossible triangle, it is a triangular impossible object, an optical illusion consisting of an object which can be depicted in a perspective drawing, but cannot exist as a solid object.

The bar was first released in 2023.
