1. What Exactly Is a Mule Error?
A mule error happens when the U.S. Mint accidentally pairs two dies that do NOT belong together.
In this case:
- Front: Sacagawea Dollar obverse
- Back: South Carolina State Quarter reverse
This is a massive production mistake — the kind that should be impossible under mint quality control.
Yet a tiny number slipped out… and the numismatic world went crazy.
2. Key Identification Features (Check Both Sides!)
➤ Obverse: Sacagawea Dollar (Front)
Look for:
Sacagawea carrying her infant, Jean Baptiste
“LIBERTY” & “IN GOD WE TRUST”
Date: 2000
Mint Mark: “D” (Denver Mint)
If the front looks exactly like a normal 2000-D Sacagawea Dollar… keep going!
➤ Reverse: South Carolina State Quarter (Back)
This is where the magic (and the value) is:
Palmetto Tree (state symbol)
Carolina Wren
Yellow Jessamine
Inscriptions:
- “UNITED STATES OF AMERICA”
- “QUARTER DOLLAR” (NOT “ONE DOLLAR”)
If your dollar coin has a quarter reverse, you may be holding a six-figure treasure.
3. Value Breakdown — Why It’s Worth $100,000+
This claim is 100% true. Verified examples have sold for:

Why It’s So Valuable:

4. 5-Step Authentication Protocol (Must Read!)
Because of its high value, counterfeits exist. Use this checklist:
Step 1 — Confirm the Sacagawea obverse
Must be:
- Sacagawea & infant
- “2000-D” date/mint mark
Step 2 — Check the Reverse
Must show the South Carolina Quarter design.
Step 3 — Verify Weight & Planchet
Should be on a dollar coin planchet:
Weight: 8.1 grams
Step 4 — Check Die Characteristics
Only PCGS/NGC can analyze microscopic details.
Step 5 — Submit for Professional Grading
Absolutely mandatory.
Only PCGS or NGC can authenticate this mule beyond doubt.
