Great looking broadstrike, and quite large. A common year for buffalo nickel errors, making this a particularly affordable example.
A broadstrike occurs when a coin is struck outside of the collar die, which results in the coin expanding beyond its normal size or diameter. The coin will not have any edge devices since it was struck out of collar, and therefore did not receive a “strike” from the collar die.
PCGS MS-64 with brilliant white luster.
