A 1966 Series E savings bond is worth $121.94 to $128.13 per $25 of face value (the amount printed on the bond) in November 2026, by issue month.
A $100 bond is worth $487.76 to $512.52, and a $10,000 bond $48,776.00 to $51,252.00. January and February issues are worth the most, March and April the least.
Every 1966 bond stopped earning interest in 1996, after 30 years, so these values are final and unchanged since then. They come from Treasury's published value files, with 8 face values in every month. The letter on the bond is E, never EE.

A 1966 Savings Bond Is Series E, Never Series EE
A savings bond dated 1966 is a Series E bond, because Series EE began in January 1980 and every bond dated May 1941 to June 1980 is Series E. A "1966 EE bond" does not exist, and an EE chart gives a wrong value. See how Series EE savings bonds, sold from 1980, differ.
Why Every 1966 Bond Stopped Earning Interest in 1996
Every 1966 Series E bond reached final maturity (the date interest stops) between January 1 and December 1, 1996, 30 years after its issue month (31 CFR 316.8(b)). The list gives the four facts that fix the 1966 life.
- Issue: January to December 1966, at 75% of face
- Maturity group: issues December 1965 to June 1980, with final maturity December 1995 to June 2010
- Life: 30 years, and 1966 is the first full issue year under it
- Final maturity: the first day of the issue month, in 1996
The value has not changed since final maturity. Other savings bonds mature and stop earning interest at other dates.
Why a 1966 Bond Is Worth Less Than a 1956 Bond That Also Stopped in 1996
A 1966 bond is worth less than a 1956 bond because it earned for 30 years and the 1956 bond for 40, though both stopped in 1996 (31 CFR 316.8(b)).
A $100 bond is worth $487.76 to $512.52 from 1966 against $747.16 to $798.24 from 1956. The 40-year life ended with November 1965 issues ($736.12 per $100), so read the issue date.
March and April 1966 Issues Carry the Year's Lowest Value
March and April 1966 issues are worth $121.94 per $25 ($487.76 per $100) in November 2026, the lowest of any Series E issue month from December 1965 through February 1978. January and February 1966 ($128.13 per $25) outrank every E month issued December 1965 through May 1967.
Why a January 1966 Bond Is Worth More Than a December 1966 Bond
A January 1966 bond is worth more than a December 1966 bond because each issue month reached its 30-year final maturity at a different date, and the value file prices the 12 months in seven groups.
A $100 bond is worth $512.52 from January and $503.40 from December, and $24.76 less from March than from January.
The large fall comes from February to March, $6.19 per $25, plus a $0.01 dip from June to July. Values then rise or hold to January 1967. Table 2 groups the months that share one value; December 1965 ($128.12) and January 1967 ($125.86) share none.

Note: values do not rise every month in 1966; they fall $6.19 per $25 from February to March and $0.01 from June to July, and rise or hold from July 1966 to January 1967.

What a 1966 Bond Cost and How It Grew for 30 Years
A 1966 Series E bond cost 75% of face: $18.75 for a $25 bond, $75 for a $100 bond and $7,500 for a $10,000 bond (31 CFR 316.2(b)).
Its interest sits inside the value (31 CFR 315.30): a $100 bond carries $412.76 to $437.52 of it, 6.50 to 6.83 times its price. Buying at half of face belongs to paper Series EE, not to this bond.
Which Face Values Were Issued in 1966: Eight, From $25 to $10,000
Treasury's calculator prices 1966 Series E bonds in 8 face values in every issue month: $25, $50, $75, $100, $200, $500, $1,000 and $10,000. The list gives each price and 1966 range.
- $25: $18.75 ($121.94 to $128.13)
- $50: $37.50 ($243.88 to $256.26)
- $75: $56.25 ($365.82 to $384.39)
- $100: $75 ($487.76 to $512.52)
- $200: $150 ($975.52 to $1,025.04)
- $500: $375 ($2,438.80 to $2,562.60)
- $1,000: $750 ($4,877.60 to $5,125.20)
- $10,000: $7,500 ($48,776.00 to $51,252.00)
The calculator priced the $10 bond only through March 1950 and has no $5,000 Series E.
Which Savings Bonds Were Sold in 1966: Series E, Series H and Retirement Plan Bonds
A savings bond bought in 1966 is one of 3 kinds: Series E (75% of face, interest added to the value), Series H (face value, interest paid every six months) or a Retirement Plan Bond (face value, from January 1, 1963; 31 CFR 341).
Series H and Retirement Plan Bonds go by mail with FS Form 1522; banks may not pay Series H (31 CFR 321.7(a)).
Savings Notes (Freedom Shares) went on sale May 1, 1967 (31 CFR 342.0), so no Savings Note is dated 1966. Series J and K ended in April 1957 and F and G in April 1952.

How to Find the Exact Value of Your 1966 Savings Bond
Treasury prices a 1966 Series E bond by its issue month and face value; the serial number and the name printed on it do not change the value. Our savings bond calculator, built on Treasury's published value files, prices paper E bonds.
- Check that the bond says E.
- Read the issue date on a paper savings bond, upper right (31 CFR 316.2(c)(2), (d)).
- Ignore the validation date, lower right.
- Read the face value printed on the bond.
- Find the row and column in Table 1; February and March issues differ by $24.76 per $100.
TreasuryDirect, Treasury's savings bond website, has a free calculator that marks E bonds "MA". A 1966 bond need not show a Social Security number; one was required only on bonds issued from January 1, 1974 (31 CFR 316.2(c)(1)).
Cashing a 1966 Savings Bond and Reporting Its Interest
A 1966 Series E bond is cashed at a financial institution that cashes savings bonds or by mail with FS Form 1522, and Treasury charges no fee. Read how to cash savings bonds by each route.
Banks may cash paper bonds but need not (FS Publication 0022, Rev. October 2022), and may not charge you (31 CFR 321.23(c)). You write your Social Security number on the bond (31 CFR 315.39(a)).
FS Form 1522 (Revised April 2026; PDF, TreasuryDirect) goes with the bond to Treasury Retail Securities Services, P.O. Box 9150, Minneapolis, MN 55480-9150. Treasury says 3 months or longer in your name, 5 months or longer if not (November 11, 2026); see how to cash by mail with FS Form 1522.
The $1,000 test is the total on the form. At $1,000 or less (one March $200 bond, $975.52), sign and enclose an ID copy. Above $1,000, a notary or certifying officer certifies your signature: one January $200 bond ($1,025.04), two December $100 bonds ($1,006.80) or any $500 bond ($2,438.80 and up).
Tax Year 1996: When Interest on a 1966 Bond Was Reportable
Interest on a 1966 bond that was never cashed became reportable for tax year 1996, the year of its final maturity, unless reported earlier (31 CFR 316.9; IRS Publication 550).
Interest is the value minus the price, $412.76 to $437.52 per $100 bond, and taxed by federal income tax only; it is exempt from state and local income tax (31 U.S.C. 3124; 31 CFR 316.9(a)). Ask a tax professional about a missed year; see the rules for federal tax on savings bond interest.
Lost, Found or Inherited 1966 Bonds
Five situations change what an owner or heir does with a 1966 bond: lost, inherited, inherited with unreported interest, found, or held in Treasury records only.
Table 4: Lost, found or inherited 1966 bonds
| Situation | Rule for a 1966 bond | Link |
|---|---|---|
| Lost, stolen or destroyed | Claim on FS Form 1048 (Revised March 2026). Claims 6 years or more after final maturity need the serial number (31 CFR 315.29(c)); for 1966 bonds that is 2002 at the latest (our calculation). Treasury's 2024 Report to Congress (March 11, 2025) said records from October 1957 onward, 97% of matured unredeemed bonds, were digitized. Treasury Hunt has been unavailable since September 30, 2025. | FS Form 1048 claim for lost, stolen or destroyed savings bonds |
| Owner has died | The surviving "OR" co-owner or the P.O.D. (payable-on-death) beneficiary takes the bond, otherwise the estate (31 CFR 315.70). | savings bonds after death |
| Inherited, interest never reported | If the owner died before the bond's final maturity, interest earned before death is income in respect of a decedent unless reported on the owner's final return. If the owner was alive at final maturity, the interest was reportable for that year (26 CFR 1.454-1(a)(1); IRS Publication 550). | taxes on inherited savings bonds |
| Found among papers | The value comes from Table 1. Check the owner, co-owner and beneficiary first. | found old savings bonds |
| Held in Treasury records, not in hand | For a bond more than 3 years past final maturity, Treasury may share the owner's name and address with a State that has an information-sharing agreement, only to locate the owner (31 U.S.C. 3105(f); 31 CFR 323.11; rule 89 FR 102735, December 18, 2024).
