How should I fill out the lost bond form from the Department of Treasury? I think I may be missing a bond I bought in 2003, but have no way of knowing for sure until I have the fed do the research on it. Should I include every I-bond I have, w/ serial numbers and such, knowing they probably will re-issue all of them, or should I only just list the denominations ( I own $50, $75, $100, $200 I-bonds) nebulously, and hope that find the missing bond in the process, if one is missing? I just want them to let me know if I am missing a physical paper bond, and thus get that one re-issued, but the form is more involved than that. There is no place on the form that allows me to tell them that I think I have my bonds all accounted for but one might be missing and need help figuring out if that is the case.
