Most US currency is very small and constitutes a choking hazard. This is especially true for pennys, nickles, dimes and quarters, but also for paper currency of all denominations.
Inscribing a warning the the currency itself constitutes a chocking hazard is not only a prudent step for consumer safety but also a poetic statement about our currency that reflects the feelings of the US people in the early 21st century.
Adding a choking hazard warning to Minted US currency is both a valid and true statement regarding consumer safety as well as an accurate artistic expression in the post stimulous fall out.
Future Generations and historians will look to the choking hazard on US currency and have a better interpretation of early 21st century america.
