You're absolutely right. I just made the simplest calculation.
Let's take it one step further.
Stack the coins in neat columns and arrange the columns next to each other in a triangular way. The mass you get is filled for 78.5% (the fraction is Pi/4) with coin and 21.5% air.
This means that, continuing the euro example, the bottle contains 996 (and a quarter) 10 cents coins, weighing 4.08 kilo, and costing you 99.6 euro. A bit less then the champagne price. [img]smile.gif[/img]
This is still not the actual amount of coins you can fit in a bottle. You will probably lose more space due to its shape.
