The 1988-S Kennedy Half Dollar is worth anywhere from $5 in lightly circulated condition to over $15 or more in pristine proof quality — and if you have an ultra-deep cameo example, collectors may pay significantly higher. Found one in an old collection? Read on to find out exactly what you have.
What Is the 1988-S Kennedy Half Dollar?
Before we talk dollars and cents, let’s cover the basics. The 1988-S Kennedy Half Dollar was struck at the San Francisco Mint exclusively as a proof coin. That “S” mintmark tells you right away this coin wasn’t made for everyday pocket change — it was produced for collectors as part of the 1988 U.S. Proof Set. These coins were struck using specially polished dies and planchets, giving them that mirror-like finish you might notice right away.

The Kennedy Half Dollar series has been running since 1964, honoring President John F. Kennedy. By 1988, the half dollar had largely disappeared from circulation, making the proof version from San Francisco the only way most collectors could add a 1988-dated half dollar to their sets. Proof coins are generally struck twice by the dies, producing razor-sharp details and deep contrast between the design and fields — qualities that serious collectors look for.
How Much Is the 1988-S Kennedy Half Dollar Worth Today?
Here’s what most people really want to know. The value of the 1988-S Kennedy Half Dollar depends on its grade, surface quality, and whether it’s been certified by a professional grading service like PCGS or NGC.
Most 1988-S proof halves grade between PR-65 and PR-69. The key factors that push value higher are the cameo or deep cameo designations — these describe the frosted, matte-looking portrait of Kennedy against the mirror-like background. Deep Cameo (DCAM) examples are the most desirable.
| Grade | Designation | Estimated Value |
|---|---|---|
| PR-65 | No Cameo | $5 – $8 |
| PR-67 | Cameo | $8 – $12 |
| PR-68 | Deep Cameo | $10 – $18 |
| PR-69 | Deep Cameo | $15 – $30 |
| PR-70 | Deep Cameo | $100+ |

Factors That Affect the Value of Your 1988-S Half Dollar
Not every 1988-S proof half dollar is worth the same amount. Several factors can push your coin’s value up — or down.
Surface condition: Proof coins are fragile. Even minor hairlines from improper cleaning can drop a PR-69 down to a PR-65 or lower. Never clean your coins. If you have one that looks dull or spotted, it may have been cleaned at some point, and that hurts value considerably.
Cameo contrast: As mentioned, the cameo and deep cameo designations matter a lot in this series. A PR-68 Deep Cameo is far more sought after than a plain PR-68.
Certification: Coins graded and slabbed by PCGS or NGC are easier to sell and typically command higher prices. Raw, uncertified coins are harder to price and sell.
Original packaging: If your 1988-S half dollar is still sealed in its original U.S. Mint proof set packaging, that’s a good sign. It suggests the coin hasn’t been mishandled, which protects its grade — and its value.

How to Get the Best Price for Your 1988-S Kennedy Half Dollar
If you’re thinking about selling, you have a few solid options. Online auction platforms like eBay allow you to reach a wide collector base. Coin shows are another great option where dealers can assess your coin in person. Local coin shops can offer quick cash, though they’ll typically offer below retail value since they need to resell.
Before selling, consider using CoinHix to research current market values. CoinHix gives you real-time price data based on recent sales, so you won’t go in blind when negotiating. It’s one of the best tools for everyday people who want to know what their coins are actually selling for — not just what someone hopes they’re worth.
For coins you think might be high grade, professional grading through PCGS or NGC is worth the cost. A coin graded PR-69 DCAM will sell for meaningfully more than the same coin sitting raw in a flip.
Is the 1988-S Kennedy Half Dollar Rare?
In short — no, it’s not particularly rare. The U.S. Mint struck over 3 million proof sets in 1988, so there are plenty of these coins around. However, coins in the highest grades (PR-69 and PR-70 with Deep Cameo) are genuinely scarce, and those are the ones collectors hunt for.
If you’re building a proof Kennedy Half Dollar set, the 1988-S is a must-have but not a budget-buster. It’s an affordable, beautiful coin that’s a great entry point for new collectors. And if you’re just looking to sell what you found, even an average example in original Mint packaging can fetch $5–$10 from a collector.
CoinHix makes it easy to track down fair market pricing for this exact coin, so whether you’re buying or selling, you’ll always know where you stand.
FAQ
Q: Is the 1988-S Kennedy Half Dollar made of silver?
A: No. The 1988-S proof Kennedy Half Dollar is made of a copper-nickel clad composition — 75% copper and 25% nickel. Silver proof Kennedy Half Dollars were reintroduced by the Mint starting in 1992, so the 1988-S does not contain any silver.
Q: How do I know if my 1988-S half dollar is in proof condition?
A: A genuine proof coin will have a mirror-like reflective field (the flat background areas) and often a frosted, matte-looking design. If your coin looks shiny and sharp all around, it’s likely a proof. The “S” mintmark on the obverse (under Kennedy’s portrait) also confirms it came from the San Francisco Mint as a proof issue.
Q: Should I get my 1988-S Kennedy Half Dollar professionally graded?
A: It depends on the coin. If your coin appears to be in near-perfect condition with strong cameo contrast, grading through PCGS or NGC could increase its value significantly — especially if it comes back PR-69 or PR-70 Deep Cameo. For average proof examples, grading costs may outweigh the return, so it’s worth checking current market prices first before investing in certification.
