Was the 100000 dollar bill the largest amount ever made?

Yes. These bills were only printed for use in transferring large amounts from one government department to another. Only a tiny number were printed and they were never put into general circulation.

The largest circulating bill was worth $10,000. It was last printed in 1945, although it carried a series date of 1934. Distribution of high-value bills ended in 1969. They're still technically legal to spend at face value but are worth more to collectors.
