Nice one !
When I owned a few launderettes, customers were always wanting me to put in change machines. I vetoed it on security grounds. As you always have to give out exactly the value that your customer has put in there is no profit, hence no upside to count against the inevitable occasional ripping off the wall events!
Something to remember when you install it in the playground :lol:

Surely if the 'price' is clearly displayed, there is no absolute requirement to dispense same value as is inserted....
People can always choose if your 'price' is attractive or not.
The word 'change' may have some legal implication.
The 'reverse change' machines in supermarkets which 'convert' small change to notes give out only a percentage of face value of the coins that are fed in.
