Is there a 1 million dollar silver certificate?

Answer 1

There has never been a genuine US $1M bill. Many novelty companies sell fake $1 million bills. They cost a couple of dollars and are used as joke items.

The US once printed bills up to $10,000 for regular circulation use, but printing ended in 1945 and distribution was halted in 1969.

There were about 42,000 $100,000 bills printed for special government transactions but these were never publicly circulated. All but one or two were later destroyed.
