hold up to $3 in dimes

They're so small that it can get frustrating trying to distinguish one from another since they're about the size of a penny and tend to get jumbled together, however there is a way to separate them with ease - just create a narrow slit to clearly see how full your dime holder is! A little fine-tuning should make all the difference. I haven't had a chance to print this out yet, but based on my calculations, it's likely going to be pretty accurate.
