What year was the US 5000 dollar bill taken out of circulation?

The $5000 bill has never been withdrawn from circulation and technically remains legal tender, although it would be very difficult to spend one.

The final series of high-denomination bills began in 1934 and continued to be printed with that date until 1945 when production ended due to low demand. It was still possible to request high-value bills from banks until 1969, when President Nixon ordered a halt to their distribution in an effort to combat their use in criminal activities. Banks were in addition required to hold any bills that were brought in and redeem them to the Treasury, but there was no wholesale withdrawal and they were never demonetized.
