NGC vs. PCGS: Is a 1972-P Kennedy Half-Dollar Crossover Worth the Crack-Out?

Sometimes a plastic holder is holding the coin back. That is the tempting promise of a crossover: crack out a coin graded by one service, submit it to another, and hope for a higher grade or a more collector-friendly designation. I have seen that upside, but I have also seen what happens when a coin leaves its holder with fresh marks. Let’s weigh the risks and rewards of an NGC-to-PCGS crossover using a 1972-P Kennedy half dollar with a triangular punch-like feature and suspected acid alteration as the practical example.

When I consider an NGC-to-PCGS crossover, I do not do it simply because the coin looks dramatic. I ask whether its original surfaces, strike, luster, eye appeal, or variety attribution could reasonably be judged differently. At best, PCGS may assign a higher numeric grade or recognize a variety that changes the coin’s collectibility and numismatic value. At worst, the second opinion is lower, and the coin pays for another holder, return shipping, and handling. Documented provenance may add interest, but it cannot turn damaged surfaces into mint condition.

For this 1972-P Kennedy half dollar, the first grading question matters most. The triangular feature may catch the eye, but dramatic does not automatically mean mint error. If the mark and altered surfaces were created after production, resubmitting the coin in hopes of an NGC-to-PCGS upgrade is likely to be an expensive disappointment.

First Identification: Mint Error or Post-Mint Damage?

In numismatic catalog notation, this Philadelphia issue is written 1972-P, even though no letter “P” appears as a mint mark on the coin. Philadelphia half dollars of this date normally have no mint mark, while Denver examples carry a “D.”

The 1972 Philadelphia issue is a copper-nickel clad circulation coin with a weight of 12.5 grams, a diameter of approximately 30.6 millimeters, and a reeded edge. Its outer layers are 75% copper and 25% nickel. It is not a silver half dollar. That distinction is worth emphasizing because the 1964 Kennedy half is 90% silver, while the 1965-1970 issues are 40% silver. By 1972, standard circulation issues had returned to the copper-nickel clad composition.

According to the forum descriptions, the reverse displays a triangular punch-like feature and areas that may have been affected by acid. The working diagnosis was post-mint damage or alteration rather than an official mint error. That is the sound starting point unless physical evidence proves otherwise.

How I Tell an Alteration from a Genuine Mint Anomaly

A genuine mint error begins during production. A doubled die, struck-through error, clipped planchet, incomplete planchet, or similar defect should show features consistent with the striking process and the way metal responds under pressure.

A post-mint alteration generally looks different:

• Hard or unnatural edges: The boundaries of a triangular depression may be sharp, crude, or surrounded by displaced metal in a way that does not match the strike.
• Burrs inconsistent with minting: A hand punch can lift, fold, or tear metal in ways that a striking die would not.
• Broken surface continuity: Cuts or deformation may interrupt original luster rather than flow naturally with the surrounding struck metal.
• Acid-related texture: Etching may create roughness, pitting, discoloration, detail loss, or an unnatural-looking patina.
• A poor relationship to the design: The mark may obscure lettering or cross unrelated elements without showing the metal flow expected from a genuine striking error.
• Tool or edge evidence: Careful inspection may reveal a filed area, edge disturbance, trapped residue, or another sign of later handling.

None of those observations can be confirmed conclusively from a handful of internet photographs, but they are the markers I use when examining an altered coin in person. I compare the feature with authenticated examples, inspect the edge under magnification, and check whether the luster and surface texture remain consistent with the rest of the coin. A triangular depression is not, by itself, a recognized rare variety. It is simply a triangular depression until the evidence establishes its origin.

What the Possible “No FG” Status Really Means

One forum response raised the possibility that the coin might also lack reverse designer Frank Gasparro’s “FG” initials. That observation deserves careful checking, but it should not be accepted at face value. A missing initial can become a cataloged variety only when its absence is verified against authenticated examples and the expected die period.

If the triangular alteration has damaged or concealed the relevant portion of the reverse, it may be impossible to determine whether an initial is truly absent. Even if the coin has a legitimate “no FG” variety, that status does not erase acid damage or automatically earn a major-error premium. Its numismatic value still depends on the combination of rarity, mint condition, eye appeal, and formal recognition.

NGC and PCGS each maintain detailed standards for recognized varieties and mint errors. A seller’s dramatic description, forum consensus, or eye-catching terminology cannot replace that review. Before paying for a crossover, I would want a high-resolution, straight-on image of the complete reverse, close views of the mark, edge photographs, and comparisons with authenticated varieties. The coin’s grading history and provenance should also be documented, but provenance alone cannot authenticate the feature or repair its condition.

What an NGC-to-PCGS Crossover Can—and Cannot—Change

An NGC-to-PCGS crossover means removing the coin from its NGC holder, examining it under PCGS’s standards, and submitting it to the second service. The reward can be a higher numeric grade, a more appropriate classification, or recognition of a verified rare variety, any of which may affect numismatic value. The risk is equally real: handling can create a scratch or edge nick, and PCGS may see even more reason for a conservative grade. Neither service can turn post-mint damage into a mint error, restore original luster, or manufacture mint condition. My rule is simple: I cross a coin only when a specific, evidence-based reason outweighs the cost. If the goal is merely to replace one slab with another, I leave it alone.
