Nope. I remember during the August 1999 run of Millionaire, Tom Coletta's $16,000 question specifically talked about what was on the back of a $20 bill. Choices were the Lincoln Memorial, the US Capitol, the White House, and the US Treasury Building.
Regis told him that no, he couldn't check his wallet. So, Tom used the 50:50 and still got it wrong. He said it was the US Capitol, but it was the White House, so Tom left with $1,000. That translates into 500 $20 bills!
