hanges to the design, while generally small, occur with regularity.  Series were the design spans several decades are highly susceptible to being tweaked periodically as technology improves and old master hubs begin to show wear.  Series where there are high mintages also see more frequent design changes as mint personnel attempt to maximize die life.  Design changes also tend to occur early in the history of a design as the kinks of production and circulation wear are addressed.

For the most part these design changes go unnoticed.  But for the ardent numismatist, they are diamonds in the rough, just waiting to be discovered.  Competing designs are often placed into production side by side until old dies are past their production life.  Thus the differing designs can be found with ease.  Sometimes, however, the old design is retired quickly or the new design slips in at year's end or accidentally and a rarity is born.

Since the mint kept few records of such changes, it is left to the numismatist to discover them on his own.  It has only been since the variety revolution of the last 25 years that many of these design changes have been cataloged.  An increasing number are being added to the informational databases as cherrypickers diligently inspect every coin they come across, looking for that elusive variety for their collections.

Re-engraved Designs

Though technically a die error, the re-engraved design (RED) is usually collected as a sub-category of the design change.  Occasionally a design element is accidentally removed through abrasion and then re-engraved by hand.  Currently this is a rare category with only a small handful of confirmed specimens and most of them on proof coins.
