The Sacagawea dollar is often dismissed as a modern, low-value coin—but one rare Sacagawea dollar error has been linked to valuations approaching $21 million, making it one of the most talked-about coins in modern numismatics. While most Sacagawea dollars are worth just $1, a handful of extraordinary mint errors and ultra-rare varieties have rewritten what collectors thought was possible.
This guide explains which Sacagawea dollar is worth millions, why it’s so valuable, and how collectors can identify rare examples.
Why the Sacagawea Dollar Can Be Worth Millions
Introduced in 2000, the Sacagawea dollar was intended for circulation but never gained widespread use. Despite high mintages, value explodes when a coin features:
- A historic mint error
- A unique die pairing (mule)
- Wrong metal composition
- Extremely limited surviving examples
- Strong auction provenance
Only one Sacagawea-related error type is associated with multi-million-dollar valuations.
