How much does Alaska cost?

Well, in 1867 it cost the United States of America $7.2 million. Russia offered to sell Alaska to the US in 1859, but the purchase was delayed due to the Civil War. After the war, Russia made the offer again, and on March 30, Secretary of State William Seward accepted the offer. The Senate approved the purchase on April 9 and President Andrew Johnson signed the purchase treaty on May 28. Alaska was formally transferred to the United States on October 18,1867. Alaska covers 375 million acres. So at $7.2 million for 375 million acres ain't to bad.
