1998-S Kennedy Half: Matte Finish Special Issue
Coin Encyclopedia · 8 min read · Published November 7, 2026
The 1998-S Kennedy half is the strangest Kennedy half of the modern era: a coin struck in 90% silver, with a soft matte finish, issued only as part of a commemorative set — and never meant to circulate. It was made for the Robert F. Kennedy commemorative silver dollar set of 1998, a special issue with a small mintage and a finish unlike any other Kennedy half. If you own one, it came from that set, because there was no other way to get it.
The matte finish is the whole coin. It is not a proof — there is no mirror shine — and it is not a business strike — there is no bright lustre. It is a soft, grainy, almost sandy surface, struck that way deliberately, and it is the first thing a collector checks. A 1998-S with its matte finish intact is a special-issue coin; one that has been polished or dipped is a damaged one.
The Robert F. Kennedy set — why this coin exists
In 1998 the Mint issued a commemorative silver dollar honouring Robert F. Kennedy, and alongside it a special Kennedy half dollar in matte finish — a pairing of two brothers, one on each coin. The half was struck at San Francisco in 90% silver, the old composition, with a matte finish that set it apart from every other Kennedy half. It was issued only with the commemorative set, in small numbers, to collectors.
That origin is what makes the 1998-S a special issue rather than a date in the series. It is not part of the regular run of Kennedy halves — it is a one-off, made for a single occasion, and its mintage is small by the standards of a coin the Mint strikes by the millions. Collectors who chase modern special issues know it well; collectors who only build date sets often miss it entirely.
The matte check — reading a finish that is easy to ruin
Hold the coin under a good light and look at the surface. A genuine 1998-S matte finish is soft and grainy across the whole coin, with no mirror areas and no bright shine — it looks almost like fine sandpaper under magnification, even and dull. That is the finish as struck, and it is the coin's identity.
The danger is that the finish is easy to destroy. A dip in cleaning solution strips the matte texture and leaves a bright, shiny surface; polishing does the same, and worse. A 1998-S that shines like a proof or a business strike has been ruined, and its premium is gone — the matte finish is the coin, and without it there is nothing special left. Never clean a matte finish coin, and never take one that looks polished.
Silver again — the old composition returns
The 1998-S is struck in 90% silver, the composition of the 1964 halves, at the old weight of 12.5 grams. That was a deliberate choice: the coin was a commemorative issue, and the Mint used the classic silver composition rather than the clad metal of the regular 1998 halves. It carries 0.36169 troy ounces of pure silver, the same as a 1964.
But the silver is not the point of the coin — the finish and the issue are. A 1998-S is worth more than its silver because it is a small, special issue with a finish no other Kennedy half has, not because of the metal in it. Judge it on the matte surface first, the originality second, and the silver last.
The 1998-S in a collection — the special issue most sets miss
Most Kennedy sets do not include the 1998-S, because it is not a regular date — it is a special issue, and many collectors never hear of it. That is exactly why it is worth knowing about: it is the kind of coin that separates a complete collection from a thorough one, and it is affordable enough that the only barrier is knowledge.
If you pick one up, take it with its finish intact and, if possible, with its original set packaging. The set is the provenance: it proves the coin is what it claims to be, and it protects the matte finish from the handling that ruins it. A 1998-S in its original set, untouched, is the right example — and the one that will still be a special issue in fifty years.

No researched grade figures exist for the 1998-S matte finish yet. It is a special issue, not a circulation coin, so its market is judged on the matte finish itself — a worn or polished example loses the very thing collectors pay for.
Specs — a silver special issue with a matte finish
The 1998-S matte finish half is a 90% silver coin weighing 12.5 grams, carrying 0.36169 troy ounces of pure silver — the old silver composition, revived for a special collector issue. The live metal floor for this coin is —: our live system publishes no floor for this issue, so the grade table above and the reported results below are the guide to follow.
Gilroy Roberts' portrait of John F. Kennedy fills the obverse, adapted from the medal he made for the 1961 inauguration, while Frank Gasparro's reverse is based on the presidential seal. Diameter 30.6 millimetres, reeded edge, and the mint mark on the reverse below the eagle's left talon. The matte finish is the giveaway: a soft, grainy surface unlike the mirror finish of a regular proof or the shine of a business strike.

Your 1998-S Kennedy Half Matte finish questions, answered
How much is a 1998-S Kennedy half dollar worth?
Our guide has not yet researched grade-by-grade estimates for the 1998-S matte finish, so the table shows dashes. It is a small special issue issued only with the Robert F. Kennedy commemorative set, and its value rests on the matte finish — a polished or dipped example loses the premium.
Is the 1998-S Kennedy half silver?
Yes — it is 90% silver, weighing 12.5 grams with 0.36169 troy ounces of pure silver, the classic composition revived for this special issue. The regular 1998 halves are copper-nickel clad; only the matte finish special issue is silver.
What is the matte finish on the 1998-S Kennedy half?
The matte finish is a soft, grainy, even surface with no mirror shine and no bright lustre, struck that way deliberately for this special issue. It is the coin's defining feature — and it is easily destroyed by cleaning or polishing.
How many 1998-S matte finish Kennedy halves were struck?
Our catalog has not recorded a mintage figure for this special issue, so none is given here. It was a small issue issued only with the Robert F. Kennedy commemorative set, and far fewer exist than any regular-date Kennedy half.
How do I tell a real 1998-S matte finish from a regular proof?
The matte finish is soft and grainy with no mirror shine, while a proof has deep mirror fields. The coin must also carry an S mint mark on the reverse below the eagle's left talon and weigh 12.5 grams in 90% silver.
