Treasury Direct is the biggest rip off going right now. They make it easy to buy bonds but good luck redeeming them and getting your money back. They require your bank to use their Corporate Seal or Medallion to verify your identity. The problem is that banks are not in the business of verifying identity for someone else and their Seals and Medallions are usually at the corporate headquarters. Several banks that I spoke to said they thought the form was a scam. They said that the Department of Treasure more than anyone else should know banks are not going to execute a document with their official seals for what amounts to an affidavit of identity
