FORM 1522 For Redeeming Paper EE Savings Bond Confusion

Hi - I have several paper EE Savings Bonds that have reached maturity that I would like to send in for payment. The total value of the bonds exceed $1000 so I will have the form notarized.

Nowhere on Form 1552 do they explain what to do with the bond. Do I sign the back of the bond? Does each bond need to be notarized or only my signature on Form 1552.

Can anyone that has gone through this please share what you did and if it was successful.

Thanks
