The removal of foreign material or cleaning of coins is a delicate and often controversial topic within coin collecting (numismatics).
- Damage to surface: Cleaning, especially with harsh chemicals or abrasive materials, can irrevocably damage the coin’s delicate surface and luster, diminishing its value.
- Removal of Patina/Toning: Cleaning can remove the natural patina or toning that forms on coins over time, which collectors often value as a sign of authenticity and historical significance.
- Reduced Collectibility: Improperly cleaned coins are often considered less desirable by collectors and professional grading services may assign them a lower “details” grade, impacting their market value.
- Potential for Chemical Reactions: Some cleaning solutions can react with the metal, causing discoloration or corrosion.
- Harmless Surface Debris: Gently removing loose dirt or debris with methods like rinsing in distilled water or a soft brush may be considered acceptable.
- Harmful Contaminants: Removal of potentially damaging substances like PVC residue (which appears as green slime) might be necessary to prevent further damage, [according to APMEX].
- Expert Services: Professional conservation services, such as those provided by Numismatic Conservation Service (NCS), offer specialized, non-invasive techniques to remove harmful contaminants and stabilize coin surfaces.
- Conservation vs. Cleaning: It’s important to distinguish between conservation (preserving a coin’s originality by removing harmful contaminants) and cleaning (altering the surface and potentially reducing value).
- NCS Techniques: NCS employs methods to safely remove residues, haze, encrustations, and unattractive toning, often improving a coin’s appearance and long-term stability without causing damage.
Unless dealing with clearly harmful contaminants or following expert advice, collectors are generally encouraged to leave coins in their original state to preserve their value and historical integrity.
