46 million bills were in circulation for 8 months before the first person even noticed the typo, so probably not, no.

I've been a cashier, and trust me, we had more important things to do than examine bills with a magnifying glass looking for spelling errors. If a bill seemed suspicious at a quick glance, I swiped it with the counterfeit detector pen, and if it came out fine, I shrugged and put it in the register.
