<prompt> Human: Odd question, I know. But my dad told me 30 years ago that I can never throw out a check that I messed up and voided. So i have 30 years of them sitting in a drawer. I securely get rid of checks that I mobile deposit, shouldnt I also securely get rid of these?  <response>: 30 years of checks...OP this isnt the Smithsonian, lol. Shred and throw them out.
