The design variation observed on some bullion pieces struck during a specific year is defined by a subtle modification to the heraldic eagle featured on the coin’s tail side. This alteration, while seemingly minor, differentiates a portion of the year’s production from the standard design. As an example, certain specimens showcase a more pronounced or refined depiction of the eagle’s details compared to the initial release.
The significance of this design element lies in its potential to elevate the collectibility and, consequently, the monetary value of affected examples. This arises from the inherent scarcity created by the limited number of coins bearing the particular design, as well as increased interest from numismatists who pursue varieties and errors. This specific design has historical context, as it reflects the evolving artistic vision and technical capabilities of the mint during the period.
