The 1928 Silver Dollar: Key Date of the Peace Dollar Series

The 1928-S VAM-3 is officially listed among the Top 50 Peace Dollar VAMs, a designation assigned by PCGS and NGC to the rarest and most visually dramatic die varieties in the Peace Dollar series. This variety originates from a doubled hub impression on the reverse die, deposited during the hubbing process at the San Francisco Mint. The doubling was carried to every coin struck from this die, making the variety reproducible and attributable.

To recognize it, examine the reverse motto "IN GOD WE TRVST" with a 10× loupe under a raking light source. The secondary image is shifted toward the lower right of each letter, creating a visible shadow-like outline. Additional doubling appears on Liberty's hair bun and the rear tiara rays on the obverse. The "S" mintmark also sits slightly higher than normal on VAM-3, a diagnostic called "Medium High S."

Collector demand for Top 50 Peace Dollar VAMs is strong and consistent. The combined PCGS and NGC certified population sits below 140 examples as of late 2024, confirming genuine scarcity. A VAM-3 in MS64 realized $1,380 at Heritage Auctions in January 2022. At circulated grades, the variety can be authenticated without expensive slabbing, giving budget collectors access to a genuine Top 50 piece.

The 1928-P VAM-2 is a Philadelphia Mint die variety showing hub doubling on the obverse. The doubling originates from a second hub impression laid slightly out of register during the die preparation process, creating a ghost image on select design features. While not designated Top 50, it is actively collected and attributed by PCGS and NGC, carrying measurable premiums over the standard 1928-P in all grades.

To identify it, examine the short spikes of Liberty's tiara at 10× magnification — specifically the 4th through 8th short spikes from the front, where the doubling is most pronounced. The letters "IBER" in LIBERTY also show clear hub doubling: look for a secondary impression on the lower-left of "I," inside the bottom loop of "B," along the middle and lower crossbars of "E," and in the loop of "R." The reverse die on this variety is normal.

Because the base 1928-P is already a key date worth $215+ even worn, a confirmed VAM-2 attribution adds a meaningful layer of collectability. Documented retail values show premiums of $75–$150 above standard 1928-P pricing at circulated grades, with larger premiums in uncirculated condition. The variety is particularly valued by specialists who collect the complete VAM set for the Peace Dollar series.

The 1928-S VAM-3A is a sub-variety of the VAM-3 Doubled Motto and shares the Top 50 Peace Dollar designation. Like its parent VAM-3, it features the same doubled reverse motto on "IN GOD WE TRVST" with the characteristic lower-right shift in each letter. What distinguishes VAM-3A is the presence of die file lines — parallel grooves left by a tool used to polish or retouch the working die — which appear in the left obverse field and around the letters "RTY" in LIBERTY.

Die file lines are diagnostic features that help numismatists tie a coin to a specific die state and die pairing. On VAM-3A, these lines are visible to the naked eye in good lighting and can be confirmed with a 5× loupe. They appear as fine parallel scratches running at a consistent angle across the obverse field. The combination of the Top 50 doubled motto and the distinctive file lines makes this a doubly attributable piece.

VAM-3A carries a slight premium over the standard VAM-3 due to its additional diagnostic feature, which makes attribution more confident and the variety more visually distinctive. Retail values range from $150–$200 at XF-45 and $400–$500 at MS-62. An MS-65 VAM-3A would be a major rarity given the 1928-S's notorious strike weakness and the scarcity of the variety itself; no reliable public auction data exists for a gem example.

A struck-through error occurs when a foreign object — such as a fragment of wire, cloth, grease, or die debris — becomes trapped between the working die and the planchet at the moment of striking. The trapped material prevents the die's design from fully impressing on the coin's surface in that area, leaving a ghost depression, smooth void, or ghost impression of the foreign object itself. On 1928 Peace Dollars, documented struck-through errors appear most often on the obverse, particularly on the spikes of Liberty's tiara and in the left field near the date.

These errors are entirely unique to each coin — no two struck-through errors are identical. They can appear as a smooth raised spot (filled die, where the debris displaced design detail), a depression (where the debris sat against the die face), or a faint outline of the trapped object. Larger, more prominently located impressions in high-visibility areas like the portrait cheek or date command the highest collector premiums.

The 1928-P's key-date status amplifies the premium for any confirmed mint error on the Philadelphia issue. A 1928-P struck-through graded PCGS AU Details has sold for approximately $450 — and an NGC MS-63 1928-S struck-through realized over $900, representing a strong premium above the standard MS-63 value of around $650 for that mint. Prominence and location of the error in the coin's focal areas drive the final price.

Lamination errors are caused by contaminants — gas pockets, subsurface voids, or impurity inclusions — in the silver-copper alloy used to manufacture the planchet. When the planchet is rolled and struck, these internal weaknesses cause the surface layer to separate, peel, or flake. On the 1928 Peace Dollar, lamination errors can appear on either the obverse or the reverse and range from hairline surface cracks to dramatic raised flakes across major design features.

The visual presentation varies considerably. Minor laminations show as thin, curled strips of surface metal still partially attached to the coin. More severe cases show outright voids where the surface layer has detached entirely, exposing the raw subsurface metal below with a distinctive dull, matte texture. Collectors and grading services assess laminaions by their size, location, and whether any design detail has been lost beneath the flake.

The value premium for lamination errors on a 1928 Peace Dollar depends almost entirely on the severity and location. A small lamination in an open field adds little over standard value. A large lamination crossing Liberty's portrait, the date, or the eagle on the reverse can significantly raise collector appeal. An MS-63 1928-P with a pronounced obverse lamination near the date has been reported at approximately $645, while a circulated 1928-P with lamination under Liberty's face can bring over $250 above normal circulated pricing.
