The 1993 Nickel Value Guide — From 5¢ to $6,900

The Full Steps designation is not technically a "mint error" but rather a strike-quality premium that transforms the value equation for 1993 Jefferson nickels more dramatically than any other single factor. The FS designation is awarded by PCGS and NGC when at least five horizontal step lines at the base of Monticello run completely uninterrupted across the full width of the building.

On the 1993-P, the Philadelphia Mint's characteristically weak hub impression and high-speed production left the step recesses chronically underfilled. Coin metal simply did not flow completely into the deepest cavity of the reverse die. The result: PCGS has certified zero 1993-P nickels with the Full Steps designation. NGC has certified a handful, with the finest known at MS67 FS. The 1993-D performs markedly better — Denver's strikes were sharper, and certified FS examples exist up through MS67 FS.

Collectors pay a substantial premium because the FS coin demonstrates both superb die preparation and exceptional planchet quality on a date notorious for poor strike. A 1993-D MS67 FS sold for $646 at Heritage Auctions in January 2016 — compared to $633 for a non-FS example of the same grade. The premium intensifies dramatically on the P-mint side, where any FS coin would be a major registry set acquisition.

An off-center strike occurs when a blank nickel planchet slides or is fed into the press collar slightly out of position, so the obverse and reverse dies strike a coin that is not centered. The result is a crescent-shaped blank area of unstruck metal on the opposite side from where the design is shifted. Both the 1993-P and 1993-D issues have documented off-center examples ranging from minor (5%–10% off) to dramatic (30%–50% off).

Visually, you'll see Jefferson's portrait crowded toward one side, and a plain, flat rim-less arc of blank nickel on the opposite edge. More extreme strikes show only a partial date, partial portrait, or partial LIBERTY. The date must still be readable for maximum collector value — a coin with the full date showing but 30% off-center is significantly more valuable than one where the date is cut off.

Collectors prize dramatic off-center strikes because they are visually striking and represent an unambiguous manufacturing defect. Error coin specialist buyers routinely seek examples from this era. A minor 5%–10% strike might fetch $20–$40, while a spectacular 30%–50% off-center example with a readable date in uncirculated condition can command $100–$200 or more on the certified market.

A clipped planchet error happens before the coin is even struck. When the blanking punch cuts circular planchets from a long metal strip, it occasionally overlaps a hole left by a previously punched blank, or clips the edge of the strip itself. The resulting blank is missing a "bite" of metal — a curved missing area (from a previously punched hole) or a straight missing area (from the strip's edge) — and this defective blank then goes through the striking process and becomes a finished coin.

Curved clips are by far the most common type. They appear as a smooth, concave arc cut into the coin's edge where the blanking punch overlapped an earlier hole. Straight clips — where the punch hit the edge of the metal strip — create a flat, straight missing area. Multiple-clip examples, where two or more areas are missing, are rarer and command the strongest premiums. The clip area itself is thin and typically shows raised metal on the adjacent surface due to the Blakesley effect.

Jefferson nickels, according to PCGS, are among the most commonly seen series for clipped planchet errors. For 1993 issues, a small curved clip in good condition is worth around $10–$25. Larger clips removing 15% or more of the coin's circumference in uncirculated grade can bring $50–$150, with PCGS or NGC certification adding meaningful premium over raw examples.

A struck-through-grease error occurs when accumulated lubricant or debris fills the recessed design cavities of a die. When the die strikes a planchet, the metal flows into only the unobstructed recesses, leaving the grease-filled areas without impressed detail. The result is a coin where some design elements appear flat, missing, or "ghostly" while the surrounding design remains sharp and fully struck.

On 1993 Jefferson nickels, grease strikes most commonly appear as flattened or missing detail in Jefferson's hair above his ear, the date digits, or the word LIBERTY. The key diagnostic: unlike a weak strike (which weakens evenly across the coin), a grease strike selectively obliterates specific areas while leaving adjacent detail crisp. Under magnification, the affected area appears smooth and planchet-surface-level rather than raised.

Value depends heavily on severity and which design element is affected. A light grease strike showing subtle hair detail loss is worth $8–$15 — more a curiosity than a premium rarity. A heavy accumulation that fully obliterates the entire date or a major design element can be worth $20–$75 or more when certified. Date-obliterated examples, nicknamed "dateless" nickels when extreme, generate the most collector interest among struck-through-grease coins of this era.

A wrong planchet error is one of the most dramatic mint mistakes possible: a planchet intended for a different denomination or coin type makes its way into the Jefferson nickel press and receives a nickel die impression. The most common version is a nickel struck on a cent (penny) planchet — producing a smaller, lighter, distinctly reddish coin bearing Jefferson's portrait. Occasionally, nickel planchets from other denominations or even foreign coin blanks enter the press.

The visual indicators are unmistakable. A nickel struck on a copper cent planchet will be noticeably smaller (19.05mm vs. the normal 21.20mm), significantly lighter (2.5g vs. 5.00g), and show a distinctly reddish-copper color on both surfaces. The design will be weakly struck at the edges because the smaller, thinner planchet cannot fill the die cavity properly — giving the coin a characteristic "floating" design appearance surrounded by a wide, flat rim area.

Wrong planchet errors are the rarest of the documented 1993 nickel errors because they require a complete breakdown of the multi-stage planchet sorting and feeding process. Certified examples are genuine numismatic curiosities. A 1993 nickel struck on a cent planchet in collectible condition typically commands $100–$300; more dramatic or off-metal examples (foreign planchet, experimental alloy planchet) can exceed $500, particularly with PCGS or NGC certification confirming the planchet identity.
