The damage hierarchy
Damage discounts scale with severity and with how much of the market walks away. Rarity and metal content set the floor: gold and silver coins can never fall below melt, and genuinely rare dates keep collector demand even with problems.
- Light rim nicks and small scratches: modest discounts, often 10–30%
- Cleaned or polished: commonly a third to half off, more when harsh
- Holed: historically the classic damage — often 50–80% off, less punishing on rare and ancient coins
- Bent or straightened: severe discounts; check for silver/gold value
- Corroded or environmentally damaged: value depends on remaining detail; dug rarities still sell
- Jewelry mounts, solder, polish: usually reduces gold coins to near-bullion; removal marks are permanent
Holed coins: the special case
Coins were holed for necklaces, charms, and pocket protection for centuries, so holed examples of scarce early coins are common — and they are the traditional budget route into otherwise unaffordable material. A holed early US silver dollar or ancient denarius sells for a fraction of a problem-free one yet remains genuinely collectible.
Plugged holes (filled and re-engraved) are considered further alteration; graders label both. For rare issues, certified details holders keep holed coins fully tradable.
What survives damage best
Three categories hold value through almost anything: precious metal coins (melt is melt — a bent gold sovereign is still roughly a quarter ounce of gold), true rarities (a corroded 1793 chain cent is still a chain cent), and coins with historical stories, like love tokens or trench-art pieces where the alteration is the point.
Common-date base-metal coins survive damage worst: a scratched common wheat cent is simply a damaged cent. Sort accordingly before spending money on holders or appraisals.
Triage damaged finds with CoinVault Pro
The critical question for any damaged coin is what it would be worth undamaged — that anchors the discount math. Scan it with CoinVault Pro: the AI identifies the exact issue and shows live problem-free values from Numista and eBay sold data, so you can judge whether a holed or worn piece still carries real money.
Damaged rarities deserve records too: log them in the collection manager with photos and honest condition notes.
