There is NO $1,000,000 dollar bill ever produced by the United States Mint. The largest bill ever produced was the $100,000 and was a Gold Certificate, they were issued by the United States to Federal Reserve Banks only against an equal amount of gold bullion that was held by the treasury.
No, at least not in the United States. The highest denomination is a $100 bill. However, back in the early to mid 1900's there were denominations of $1,000, $5,000, $10,000 and even a $100,000 bill in 1934.
