Coin Stacking - non-magnetic - a challenge on packing and levers, for all ! Tower of Paso: a tower of similar coins (the dimensions not the date should be the same), balanced on top of a single column of 10 coins. Clean coins (not sticky!) no adhesives, no magnets, no props!

Record Holder: Largest number of similar coins Yoma 2000 December 17 Provincial School 15, Paso de Indios, Argentina 494 British pennies balanced on 1! (485 on a single column of 10).

For students, teachers, mathematicians, physicists, engineers or architects. What is the best method of achieving the highest or the widest column with similar coins, or with different diameter coins? How is the highest ratio, of height to number of similar coins, best achieved? How is the largest ratio, of maximum column width to maximum column height, best achieved? Conversely, how is the largest ratio of maximum column height to maximum column width, best achieved?
