A die break error occurs when the hardened steel die develops cracks from the cumulative stress of hundreds of thousands of strikes. As the crack deepens, a section of the die eventually fractures away entirely, creating a void. Metal flows into this void during each subsequent strike, producing a raised, smooth blob or ridge on the finished coin — a feature collectors call a cud when it extends to the rim.

On documented 2022-D examples, the break manifests as a distinctive V-shaped raised notch in the lower reverse rim, sitting directly beneath the first L in DOLLAR. The cud is smooth relative to the surrounding die-struck detail, and its raised height varies depending on how many coins were struck after the die fracture occurred — later die-state coins show a more pronounced cud.

Collectors pay a sharp premium for die break errors because they are die-specific: once that die is removed, no more coins can be created with that exact flaw. Dramatic rim cuds and retained cuds (where the die fragment stays in place) command the highest prices. One 2022-D example with a particularly prominent crack was listed at $1,000 — though verified auction sales for well-attributed, certified examples typically run $100–$300 in uncirculated grades.

A doubled-die obverse (DDO) results from a misalignment between hub and die during the die-manufacturing process. When the hub impresses the design into the working die, any rotational or translational shift between the first and second impression leaves a doubled or offset image locked permanently into the die steel. Every coin struck from that die then inherits the doubling.

On reported 2022-D examples, collectors have identified doubling on the letters Y and R in the legend LIBERTY above Kennedy's portrait. Under a 10× loupe, the inner edge of those letters shows a distinct "shelf" — a secondary, slightly displaced impression of the letter form sitting just inside or alongside the primary image. This is the key diagnostic: if the doubling appears only under magnification and creates a true shelf, it is consistent with a hub-induced DDO rather than the far more common machine doubling, which shows a flat, smeared appearance with no shelf.

Because no 2022-D DDO has yet received an official CONECA FS (Fivaz-Stanton) listing, its attribution remains collector-reported. Certified examples with clear, unambiguous doubling showing a shelf on multiple letters command the best prices; coins with marginal or single-letter doubling trade at modest premiums pending formal recognition.

Strike-through errors occur when a foreign object — cloth fiber, wire mesh, grease, debris, or another coin — becomes trapped between the die face and the planchet at the moment of impact. The obstructing material prevents full die-metal contact in that area, so the finished coin shows a region of weak, shallow, or entirely absent design detail. Each strike-through is unique because the foreign material's shape, composition, and position differ every time.

On 2022 Kennedy half dollars, strike-through evidence has been found primarily on the obverse — typically in Kennedy's facial area, neck, or surrounding field — and on the reverse in the eagle's wing and breast feather zones. Look for a softly defined, smooth depression where the design should be fully struck up; the surrounding detail will be sharp and normal, making the contrast obvious. Cloth-fiber strikes leave a woven texture impression; grease strikes produce a smooth, flat void.

Strike-through errors are particularly desirable when the affected area is on a highly visible focal point — Kennedy's face being the most dramatic location. Fabric-texture impressions, because they are visually distinctive, attract the most collector interest. Authenticated examples with clear, centered, dramatic strikes routinely reach $150–$300; smaller peripheral examples sell for $25–$75.

A clipped planchet error arises when the circular punch that cuts coin blanks from a strip of metal overlaps a previously punched hole in the strip. The result is a coin blank — and the finished coin — with a curved crescent-shaped section missing from its edge. This is called a curved clip; straight clips also occur when the punch overlaps the end of the strip. The Blakesley Effect, a diagnostic weakening of the design directly opposite the clip, confirms authenticity.

Both 2022-P and 2022-D examples with clipped planchets have been identified in the marketplace. The clip is immediately visible as a concave, smooth curved cutout where the normal reeded edge should be; the coin will also fail to sit flat. Missing clad layer errors — where the copper-nickel outer layer failed to bond, exposing the copper core — are a related planchet defect that has also been noted for 2022 business strikes and adds a dramatic color contrast.

Clipped planchet errors are among the easiest mint errors to authenticate visually, making them approachable for newer collectors. Value scales directly with clip size and location: a large clip representing 15–25% of the coin's edge on a high-grade uncirculated example commands the best premiums. Missing clad layer errors, being compositional rather than mechanical, add a separate layer of interest and can amplify value when combined with a clip.

An over-mintmark (OMM) error occurs when a die originally intended for one mint facility is repurposed at a different mint — and the original facility's punch mark either remains visible beneath the new one or was never fully suppressed. In modern coinage, mint marks are applied directly to the working die rather than punched into each coin individually, so a true OMM indicates a die-logistics error at the Mint: a San Francisco die finding its way into Denver's production line.

The reported 2022-D/S example shows what appears to be an S mint mark ghosting beneath the D, consistent with a die transferred from San Francisco to Denver. San Francisco produced only proof coinage (clad and silver) in 2022, making any D-mint coin struck on or with tooling associated with an S die particularly anomalous. The coin has additionally been described as potentially struck on a silver-content planchet, though this remains unverified — 90% silver was reserved exclusively for S proof production in 2022.

This variety carries the "most controversial" designation because it has not yet received professional certification or formal attribution from PCGS, NGC, or CONECA. Without a certified example, the claimed D/S OMM designation cannot be confirmed. However, if authenticated, this would represent one of the most significant modern Kennedy half dollar errors, given that true OMMs are rare in post-1990 coinage and the 2022 San Francisco dies are compositionally distinct from Denver's.
