The 1959 Penny Value Guide: What Yours Is Worth in 2026

The 1959 DDO FS-101 is the crown jewel of Philadelphia Memorial cent errors. It formed during die production when the working die received two misaligned hub impressions — a process error that deposited a second, slightly offset image of the entire obverse design into the die steel. Because every coin struck by that die carries the same doubled image, this is a true die variety attributed as FS-101 in the Cherrypickers' Guide to Rare Die Varieties.

Under a 10× loupe, collectors look for the most visible diagnostic on the letters of LIBERTY: each letter displays a raised, rounded secondary impression with clearly notched serifs — the hallmark of genuine hub doubling as opposed to flat machine doubling. The date "1959" and the inscription IN GOD WE TRUST also carry corresponding doubling, confirming the variety rather than a localized strike defect.

Error collectors and registry set builders both pursue FS-101 examples, creating sustained demand at every grade level. Red (RD) examples in MS64 have sold for several hundred dollars; the finest certified MS67+ RD examples approach the same five-figure price bracket as the best regular Philadelphia strikes. The FS-101 is the one variety from this inaugural Memorial year that can turn a face-value find into a meaningful numismatic asset.

The 1959-D Wheat Reverse Mule is arguably the most controversial coin in modern U.S. numismatics. Only a single example is known: a Denver cent bearing the 1959 obverse die but paired with a Wheat Ears reverse die that should have been retired after 1958. If genuine, it represents an extraordinary production failure — the Denver Mint inadvertently installed an obsolete reverse die during the high-pressure changeover to the Memorial design in early 1959.

The coin presents visually as a normal 1959-D obverse: Lincoln's portrait, the date, and a D mint mark below it. But flip it over and the reverse shows the twin wheat stalks and "ONE CENT" framing that collectors associate exclusively with the 1909–1958 series. The mismatch is stark and unmistakable — there is no design element from the Lincoln Memorial anywhere on the reverse.

The coin's authentication history is the source of controversy. It passed U.S. Treasury inspection, which verified it as a genuine government product. However, PCGS and NGC have both issued formal "No Decision" verdicts, declining to certify it due to concerns that sophisticated spark-erosion counterfeiting techniques could produce a convincing replica. The coin has sold at Goldberg Auctions for $48,300 in 2003 and $31,050 in 2010; its most recent public estimate stood at $50,000.

Wrong-planchet errors occur when a coin blank intended for one denomination accidentally enters the production line for another denomination. For 1959 Lincoln cents, the most documented example involves a cent die striking a Roosevelt dime planchet — a blank of 90% silver alloy that is both lighter (2.50 g versus 3.11 g for a cent) and slightly smaller in diameter (17.9 mm versus 19.05 mm). The high-speed, high-volume production environment of 1959 created the conditions for exactly this kind of mechanical mix-up.

Visually, the result is immediately striking: the coin appears silver-white in color rather than the expected copper-brown, and the design may look compressed or stretched because the cent die is imposing its image on a planchet sized for a different coin. The rim and overall proportions feel subtly wrong to an experienced handler even before checking the weight.

The weight test is the definitive diagnostic tool. A genuine wrong-planchet error on a silver dime blank will consistently weigh approximately 2.50 grams on a digital scale accurate to 0.01 grams. Any coin that weighs 3.11 grams but appears silver is almost certainly a plated coin — a post-mint alteration with no numismatic value. Professional PCGS or NGC authentication is mandatory before attributing this error, as plated cents are extremely common and superficially similar.

The 1959-D RPM FS-501 features one of the most visually dramatic repunched mint marks in the entire Memorial Lincoln cent series: a D/D/D triple-punch where three separate hand-applied impressions of the mint mark punch are visible at different positions and angles. This die originated in the final era of hand-crafted mint mark application — before computerized automation eliminated this type of error, die makers physically hammered a steel punch bearing the mint mark into each working die individually.

When an initial punch landed off-center or failed to make a sufficiently deep impression, the die maker would re-punch, often at a slightly different position or angle. This particular die received three separate punches before achieving an acceptable result, leaving all three impressions permanently engraved into the die steel and, consequently, into every coin struck by that die. Under a 10× loupe, the D/D/D effect appears as two additional ghost "D" shapes offset above, below, or to the side of the primary mint mark.

The RPM FS-501 represents a historically significant artifact: it documents the last generation of hand-made mint marks in U.S. coinage. By the late 1980s, computerized hubbing processes had eliminated manual mint mark punching entirely, making pre-automation RPM varieties increasingly appreciated as artifacts of traditional Mint craftsmanship. Collector demand is steady for well-struck Red examples, with MS65 RD coins having sold for $176 and MS66 RD specimens bringing over $800 at recent auctions.

BIE die breaks are a well-documented Lincoln cent collecting specialty found across dozens of dates in the Memorial series, and 1959 examples exist on both Philadelphia and Denver coinage. The error occurs when a small chip or crack develops in the die between the letters B and E of LIBERTY, creating a raised blob of metal on every subsequent coin struck by that die. The blob resembles a capital letter "I," which is how the nickname BIE originated in collecting circles.

Unlike the DDO FS-101 or the RPM FS-501, BIE errors are caused by progressive die fatigue rather than a production setup error. As dies accumulate more strikes, small stress fractures can develop in the recessed areas between letters — the narrow gap between B and E is a particularly vulnerable zone. Each coin struck after the chip forms carries the same raised "I" lump, making the error reproducible and thus detectable even on worn examples.

BIE 1959 cents are collected as an affordable entry point into the Lincoln cent error hobby. They provide accessible pocket-change hunting excitement since multiple BIE dies existed in 1959 production, and the error is easy to identify with a simple 10× loupe rather than a microscope. Circulated BIE examples typically trade for $5–$20, while well-struck uncirculated Red examples in MS64–MS65 range can bring $40–$75+ among specialists who complete date-and-mint BIE sets.
