It depends on the series and the issue date printed on the front. Rough ranges from the current Treasury tables:
- $100 EE bond (paper, cost $50): from ~$51 for recent issues to $200-$300+ for 1980s-90s bonds that ran their full 30 years.
- $100 I bond (cost $100): from ~$103 for recent issues to $300-$450+ for early 1998-2001 vintages that rode two decades of inflation adjustments.
- $100 Series E bond (cost $75): all matured — typically $400-$650+ depending on the year.
Those spans are exactly why a table of examples can't answer your question — but the official redemption tables can, to the penny. The calculator reads them directly: pick the series, choose $100, set the issue month, done.
Reading the bond's face
- Series — printed top right ("Series EE", "Series I", "Series E").
- Denomination — the big number; that's face value, not what was paid.
- Issue date — month and year, usually below the series; this drives the entire value calculation.
