I have a new commission

Can I create a piece of art for just one hundred pennies?
this is the challenge
Why am I so excited about a commission that pays one pound? 
The idea is that one hundred artists will all create a piece with a budget of just one hundred pennies each, at some point in the future these projects will be documented and be displayed together as a group exhibition that will show the effect that one hundred pounds spent on art can achieve.
I find this idea really engaging, how can I spend my one hundred pennies and what can I achieve with them?
