What is a 1973-S Kennedy Half Dollar Proof worth?
Age alone gives this coin a small premium, even worn. Sharp details and original surfaces push it higher.
What would make yours worth more:
- Grade and, for proofs, strong cameo contrast
- A die variety or minting error
For market prices, check recent sold results for certified coins in the same grade.

What to check on your 1973-S
- Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 1973 (65 million made).
- Judge the grade under good light. Check the hair above Kennedy's ear and the center of the eagle on the reverse.
Proofs from 1973 come with and without frosted devices. Coins with strong contrast are labeled Cameo or Deep Cameo and are worth more.
The story of the 1973-S
Copper-nickel clad and the bicentennial reverse (1971 to 1976)
Silver was dropped in 1971 and the half took the same copper-nickel clad composition as the dime and quarter, weighing 11.34 grams. Philadelphia returned to half dollar production that year. Denver struck more than 302 million in 1971. A 1974-D doubled die obverse shows clear doubling in IN GOD WE TRUST.
No halves are dated 1975. Coins struck in 1975 and 1976 carry the dual date 1776-1976 with Seth G. Huntington's view of Independence Hall on the reverse. San Francisco made 40 percent silver versions for collector sets in addition to clad proofs. Bicentennial halves were struck in enormous numbers, more than 520 million for circulation, so they remain common. Collectors seek the silver versions and sharp uncirculated clad coins.
How to recognize it
Gilroy Roberts' portrait shows John F. Kennedy facing left with LIBERTY above, IN GOD WE TRUST below and the date at the bottom. The reverse, by Frank Gasparro, is based on the Presidential seal: an eagle holding arrows and an olive branch surrounded by a ring of 50 stars. The mint mark was on the reverse in 1964 and has been below Kennedy's neck since 1968.
