Technical Breakdown: Physics, Metallurgy & Die Diagnostics

In 2005, the United States Mint celebrated the Lewis and Clark expedition with the Westward Journey nickel series, featuring an American bison design reminiscent of the classic Buffalo nickel. Soon after distribution from the Denver Mint, collectors discovered a dramatic variety where a deep, sharp die gouge pierced entirely through the bison's back and belly, creating the legendary 'Speared Bison' (cataloged as FS-901).

1. Die Gouge Physical Formation Mechanism:
A die gouge is an incuse gouge or scratch accidentally carved into the hardened face of a steel working die (likely caused by a mint worker's dropped tool or mechanical feeder jam).

Because coin dies are negative mirrors, an incuse scratch on the die translates into a RAISED, rounded line of positive relief on every coin struck thereafter.
2. Standard US Five-Cent Specifications:
Weight = 5.000 grams | Composition = 75% Copper, 25% Nickel | Diameter = 21.21 mm.

Frequently Asked Questions

What is the 2005-D 'Speared Bison' Nickel?

The 2005-D Speared Bison is a famous modern coin error where a deep scratch or gouge on the reverse working die created a sharp raised line that runs straight through the back of the American bison, giving the visual appearance of a spear impaling the animal.

How did the 'spear' get onto the coin die?

During production at the Denver Mint, a foreign metal object or tool slipped across the working die, carving an incuse gouge into the die steel. When blank nickel planchets were struck, metal flowed into the gouge, creating a raised line on every coin.

How much is a 2005-D Speared Bison nickel worth?

Even in average circulated condition pulled from pocket change, a genuine Speared Bison is worth $100 to $150. In Mint State 64, it sells for around $400 to $500, and top-grade MS-66 to MS-67 specimens command $1,200 to over $2,600 at auction.

How do I know if my 2005-D nickel has the real spear or just a scratch?

A genuine Speared Bison error is RAISED (it stands up above the coin's surface) with smooth rounded contours matching the metal flow of the die. A post-mint scratch is INCUSE (cut into the metal) with jagged, displaced edges.

Where was the Speared Bison struck?

All authentic Speared Bison error nickels were struck at the Denver Mint and feature a 'D' mintmark on the obverse to the right of Thomas Jefferson's portrait.

Can this coin still be found in pocket change?

Yes! Because over 448 million 2005-D nickels were released into circulation, Speared Bison errors regularly turn up in coin jars, bank rolls, and change drawers.

Is the Speared Bison recognized by PCGS and NGC?

Yes. Both major grading services recognize and certify the variety under Cherrypickers' Guide catalog number FS-901.
