This would provide multiple layers of spill-prevention.. The ziploc bags probably won't jostle open, and the tupperware container provides a hard casing to prevent the bags from small puncutres. Then the bag with the drawstring provides an additional layer of containment, if the tupperware breaks open and spill the pennies, they would be contained inside the bigger bag.

You could also just epoxy some shiny pennies to your frame! That will probably look cooler.

As in any design project, you do your due diligence and go ahead. As an inspector, I would look at your pennies in layers of protection and probably approve it with the stern warning that the Head Ref will not be happy (or your friend) if he/she sees pennies all over the playing field. Nun said!
