Penny Collecting takes up alot of space

Well, some of you may know that I collect coins, not any specific year... I collect in bulk at this point. I used to sort them all down to the year and mint (when I was younger and much more free time... and eyes that could see). This interesting site tells you how much space they take up... how much they weigh and how much space they take up. Given my storage unit, I would easily say I could make a 12 inch by 12 inch cube with them... which has some interesting stats.
