What is the interest rate on a Unites States Treasury Bond?

I have three $50 Unites States Treasury Bonds, and I was just curious to the interest rate that accumulates on the the bonds. The bonds cease interest after 30 years, and I have had mine for around 16 years, so I have no plans at the moment to collect the money.





Does anyone know how much interest is gained each year, or how much it will be worth in 30 years?





Thank you.|||If it is a Savings Bond, it will be worth $50 at the end of 30 years. It was purchased for $11 in 1993. It increases in value every year until it reaches $50. It was "sold at a discount".





If it is a 30 year bond, the interest rate is apx 6%. You would know if it was this type of bond because you would receive a check for your interest twice a year. You would get the $50 original investment back in 14 years.
