The 1822 Capped Bust Quarter stands out due to a rare denomination blunder. Instead of the correct "25C" marking, the die shows traces of an earlier "50C" denomination that was struck over. This dual-strike created a prominent "25/50c" error, making it one of the most notable early quarter varieties.

The 2009-D District of Columbia quarter features a notable Doubled Die Reverse error. Visible doubling occurs on reverse inscriptions like "DISTRICT OF COLUMBIA," "DUKE ELLINGTON," and "JUSTICE FOR ALL."

Such errors are relatively rare and prized by collectors for their uniqueness.

One of the more well-known errors among state quarters, the "In God We Rust" anomaly on the 2005-P Kansas quarter arose from grease-filled dies that caused the "T" in "Trust" to appear faint or absent.
