<prompt> Human: Hello rpersonalfinance!I just wanted to write a short post to help out some people who might be in a similar situation. This subreddit has helped me a ton, and I wanted to return the favor in a small way. Today I just went to the bank to cash in some bonds that my grandparents had given to me many years prior. Previous to cashing them, I was able to look up the value of the bonds by using the U.S Treasury Direct website When I got my final total from the teller at the bank, it was significantly lower then the value the previously mentioned website had quoted me. After looking over my summary of bonds cashed in, I realized that she had not notice the two 100 face value bonds in the sea of 24 50 face value bonds. I was able to go back to the teller, and she adjusted the amount she gave me. This ended up being an addition 124! Now I know this isnt a huge tip, and 124 is a ton in the grand scheme of things, but I am very happy I prepared by using the link above, and I hope someone else can benefit from the bond calculator as well. TLDR; Prepared for cashing bonds by visiting US Treasury direct website, saved 124  <response>: Former teller here, theres so much manual keying involved with savings bonds, whereas most of what they do is now automated. Its easy to mess these up and any help a customer can provide in regard to the bonds will help to minimize errors.I always provided the customer with a copy of the spreadsheet our teller system created and asked them to review before I submit the redemption.
