<prompt> Human: So like the title says I received three 50 savings bonds that were bought in 1996. My dad said that they are mini investments that grow and accumulate more money through interest depending on the economy. He also said that it was a common baby shower gift for older generations. No one I know has ever received them and I doubt a 20-something bank teller I live in a college town would know what to do with them. I actually really liked the idea of savings bonds and Im surprised that they arent common anymore. Two bonds started at May 1996 and the other started in June 2000. What would be their value today? Should I keep them for another 21 years?  <response>: I promise you that any US bank teller will know what a savings bond is.You can calculate the value here:
