Monster Toning vs. Artificial: Decoding Rainbow, Bag & Album Colors on Part 2 “Are These Real?” Key Date Lincolns and Buffalos

Beautifully toned coins can fetch massive premiums. But the line between natural and artificial color is razor-thin. In my years as a toning specialist, I’ve learned that eye appeal is everything when judging a coin’s story.

The forum thread “Part 2: Are these real?” is a perfect case study. Why? Because eye appeal and authenticity must be assessed together—especially with key dates like the 1909-S VDB, 1914-D, and 1931-S Lincoln cents, the 1916-D Mercury dime, and the 1937-D three-legged Buffalo nickel in the conversation. I’ve examined thousands of copper, silver, and nickel specimens under controlled lighting, and these coins demand a careful look.

The Toning Specialist’s Role in Authentication

To me, grading toning is not just cosmetic—it’s forensic. The way a coin colors tells us about its storage history, its metal composition, and sometimes whether someone tried to hide tooling or a fake mintmark.

When collector Numismaphile helped a local senior with a consignment collection, the community rightly focused on diagnostics. The “Deep N” versus “Shallow N” on the 1909-S VDB. The slope of the “B” in VDB. But as a toning specialist, I immediately studied the darkness around the mintmarks on the 1914-D and 1931-S cents. Was it dirt? Album residue? Or artificial toning applied to mask an added “S”?

Why Eye Appeal Matters in Raw Key Dates

Raw coins with five-figure retail potential demand careful tone analysis. A certified 1937-D three-legger can hit $1,000–$20,000 depending on grade. A natural rainbow crescent can add 30–100% to a coin’s numismatic value. But a suspicious brown smear around a mintmark can erase that premium overnight.

Rainbow Toning: Nature’s Premium Paint

Rainbow toning is the holy grail of eye appeal. I’ve held 1909-S VDB cents pulled from original bank rolls where the obverse bloomed from magenta at the rim into cobalt and gold at the devices. This happens when copper alloys meet sulfur and moisture over decades. That kind of patina boosts collectibility like nothing else.

How to Identify Genuine Rainbow Toning

• Progression: True rainbow toning shows smooth, concentric or crescent-shaped transitions—not blotches.
• Luster retention: Under 5x magnification, original cartwheel luster remains visible beneath the color.
• Edge consistency: Tone should wrap slightly onto the reeding or rim, showing environmental exposure rather than a dip-and-spray job.

In the forum photos, none of the suspect cents displayed this orderly spectrum. The 1931-S showed uniform darkness near the “S”—a red flag for artificial enhancement rather than a monster rainbow.

Bag Toning: The Silver and Nickel Story

Bag toning develops when coins sit in mint bags against neighbors. The 1916-D Mercury dime and 1937-D Buffalo nickel in that thread are classic candidates. Silver coins bag-toned in Philadelphia or Denver bags often show iridescent blues and purples on high points. Great strike and honest bag tone raise a coin’s mint condition appeal.

Diagnostic Markers for Bag Toning

1. Contact marks align with toned “ghosting” from adjacent coins.
2. Color is heaviest at the rim and fades toward the center unless the bag was damp.
3. On the three-legged Buffalo, check that the missing leg area tones identically to the rest—added features will not match.

I’ve handled a 1937-D with honest bag toning that brought $4,200 raw to a collector who later certified it. Contrast that with artificial versions where the “D” is outlined in black oxide to simulate age. Provenance and natural skin matter.

Album Toning: The Collector’s Patina

Album toning appears on coins stored in cardboard or vinyl albums. The 1914-D Lincoln in the senior’s group likely sat in a Whitman folder. Natural album toning creates target rings or oval halos from sulfur in the paper. That soft patina speaks to a coin’s journey.

Reading Album Tones Correctly

• Look for symmetry matching the album opening cut-out.
• Genuine album tone penetrates the recessed lettering softly.
• Artificial “album” tone is often sprayed and lacks the soft halo edge.

When forum member RedRocket questioned the 1909-S VDB mintmark, I noted the surrounding darkness did not follow album patterns—it pooled artificially. That supported the “applied S” theory and hurt the coin’s collectibility.

Market Premiums for Color: What Buyers Pay

As a toning specialist, I track auction results. Here is what color can do to numismatic value:

• A plain MS-64 1931-S Lincoln: $250–$400.
• An MS-64 with monster rainbow: $700–$1,200.
• A 1916-D Mercury with bag-blue rim: +20% over a gray specimen.
• A 1937-D Buffalo with clean original skin: baseline; with artificial tone: discounted 50%.

The forum’s respectful suggestion to submit all five key dates to PCGS, CACG, or NGC is sound. I never purchase raw 1909-S VDB or 1914-D cents because the certified population is deep and the toning can be verified by the grading label’s photo.

Artificial Toning Signs: The Thin Line

This is where the “Part 2: Are these real?” thread becomes a cautionary tale. Artificial toning is applied via heat, chemicals, or markers. It destroys eye appeal and trust.

Top Artificial Toning Tell-Tales

1. Spotting around devices: The 1931-S “S” darkness screamed applied oxide.
2. Harsh line separation: No gradual blend between colors.
3. Smell: Chemical fumes under UV light (used in my lab).
4. Luster break: Matte surface under tone indicates dipping then coloring.
5. Mintmark anomaly: As jdimmick said, “use the N in UNITED as a marker”—toning that avoids the mintmark reveals a later addition.

The 1909-S VDB was called “definitely counterfeit” due to the “Deep N” (all genuine have shallow) and the level “B”. From a toning view, the even brown wash over the “S” was inconsistent with 115 years of drawer storage. A rare variety like this deserves better.

Actionable Takeaways for Buyers and Sellers

If you are helping a senior or consigning key dates, do this:

• Photograph under 6500K light at 10x before any cleaning.
• Compare mintmark tone to field tone—mismatches mean trouble.
• Submit to NGC or PCGS; their toning comments protect market premium.
• Never rely on forum consensus alone for variety attribution; use VAM and die-marker references.
• When in doubt on color, assume artificial until proven natural by certification.

Conclusion: Collectibility and Historical Weight

The “Part 2: Are these real?” discussion underscores a truth every numismatist learns: eye appeal and authenticity are intertwined. The 1909-S VDB, with only 484,000 struck, is a cornerstone of Lincoln cent history; its toning should tell a story of pocket change or bank vault, not a counterfeiter’s brush. The 1937-D three-legged Buffalo, born from a dieshop error at Denver, deserves honest bag tone, not fabricated patina.

As a toning specialist, my verdict on the shared photos is clear—the rainbow and album hopes were overshadowed by artificial signs on the key dates, and the community’s call to certify is the only safe path. For collectors, historians, and investors alike, understanding monster toning versus artificial color is not just about premium. It is about preserving the real handshake between coin and time.
