Coin stacking competition

Who would have guessed coin stacking was a competitive activity?

The currently featured coin stack is a model of Petronas twin towers, and it looks surprisingly realistic, given it’s a stack of coins that’s supposed to look like two buildings.

A model of Petronas twin towers using mostly all dimes and a few nickles and quarters. It taken probably 4 hrs if I did it non-stop. There is a piece of card supporting the bridge in the center (that's because the bridge would have sag too much to look neat) There's not other supports holding the towers standing.
