Will a bank give you 10000 pennies if you give them 100 dollars?

Well, friend, while it's possible for a bank to exchange your 100 dollars for 10000 pennies, they might not have that many pennies on hand. You could always ask the bank ahead of time if they can accommodate your request, or perhaps consider obtaining the pennies from a coin exchange service instead. Just remember, there's always a way to make your creative ideas come to life!
