Value of an Off-Center 1999 Delaware State Quarter: What Collectors Pay

An off-center 1999 Delaware state quarter can sell for $10 to $100+, depending on:

Key Value Factors

• Degree of off-centering: 5–10% (minor) → $10–20; 20–50% (major) → $30–75; >50% (dramatic, with blank planchet visible) → $75–150+.
• Condition (Grade): Uncirculated (MS-60 to MS-70) commands premium. Circulated (AU or lower) worth less.
• Visible design elements: If date, mintmark (P/D), and "CAESAR RODNEY" are fully visible, more desirable.
• Mintmark: Philadelphia (P) and Denver (D) both produced; similar values.
• Error type purity: Pure off-center (no other errors) vs. combined errors (broadstrike, clipped planchet) — combined can increase value.

Market Context

• 1999 Delaware was the first State Quarter — high public interest, many saved rolls.
• Off-center errors are mint errors (misaligned die/planchet), not varieties. Certified by PCGS/NGC adds credibility/value.
• eBay sold listings: typical raw off-center 10–30% = $15–40; certified MS-65 40% = $80–120.

Authentication Tip

Beware of post-mint damage (vice jobs, hammered coins). True off-center errors show radial flow lines from striking pressure, not flattening from pressure after minting.
