Why not use Starbucks coffee bottles to collect spare change? They look cool and besides, they have more class than pickle jars.
9 ounce bottles will hold:
$47 dimes
$13 nickels
$4 pennies
13 ounce bottles will hold
$78 quarters
$80 dimes
$20 nickels
$6.75 pennies
note:
The amounts above are approximate. A bottle filled by putting in one coin at a time will hold more coins than if the coins are dumped in all at once.
