What was the costliest tornado?
The Topeka (KS) tornado of 8 Jun 1966 is the current record holder, when adjusted for inflation, at $1,599,537,000 in 2007 dollars. The Bridge Creek-Moore-Oklahoma City-Midwest City, OK, tornado of 3 May 1999 currently ranks first in actual dollars but third when inflation adjusted. Recent forensic work by Harold Brooks of NSSL has established that a Georgia tornado in 1973, which was listed here, had a large multiplication error in Storm Data. A top-10 damage listing is online here.
