Is That a Clipped Planchet or Just a Damaged Coin?
Seeing a chunk missing from a coin’s edge? Don't assume it's just damage! You might have a cool mint error called a clipped planchet.The Clipped Planchet Error: This happens at the mint before the coin is struck. As the long metal sheet (called a "strip") is punched into blank coins (planchets), the strip can advance incorrectly. If the punch overlaps a previously punched hole, it creates a blank that is already incomplete. When this blank is struck, it becomes a coin with a smooth, curved "clip." The metal flow from the strike creates a "bow-tie" effect on the coin's field.Post-Mint Damage: In contrast, damage that happens after the coin leaves the mint (like a bite from machinery or deliberate cutting) will have jagged, rough edges and no evidence of the metal flow from the strike.Why It Matters: A legitimate clipped planchet error has collectible value, especially if the clip is large or on an older coin. Post-mint damage typically has none. When you're trying to tell the difference, a good coin value checker can help you understand the market for genuine errors versus damaged coins.
