How many coins in a small flat rate shipping box

The person who provides the best, most complete and most accurate answer to the following question will receive a prize of one silver Roosevelt dime!
The contest however, ends tomorrow at 10am Arizona time. Here's the question:
"How many 95% copper Lincoln pennies, or how many .999 pure Canadian nickels (1955-1981) can you fit in a small USPS flat rate box?"
I will of course be the judge of which answer is the best, most complete and most accurate
Questions, feedback and jokes are encouraged. Unfortunately, there can only be one winner. Good Luck
