Tabletop Sculptures
Sculptures of various kinds can be made by balancing coins on a flat surface in a variety of ways. Here are some examples.





The Australian 50 cent piece is a 12 sided polygon. A neat balance is to try balancing multiple coins on top of each other, or balancing round coins on top of a 50c piece.
