What is the value of the most expensive US 1934 10 dollar bill?

The government printed special bills for use by troops in North Africa during WWII. They had different colored seals and bore the date 1934 even though they were made about a decade later. These are the rarest of the $10 series - a bill with a yellow seal but no series letter under the date might sell for $1200.-$5000. at auction in circulated condition. An uncirculated one might go for over $10,000.
