How to Ruin A Coin

This article is about what NOT to do to your coins.

Cleaning
This is a process when someone polishes a, possibly valuable, coin. They want to do this to make it "shiny" and "worth more money". Trust me, it is not helping the coin at all.





Touching
When you touch a coin from the Obverse and Reverse, your oils get on the coin. It can cause scratching and discoloration on the coin over time.

Spitting
I don't mean to go "SPIT" on your coins. I mean when you have coins out and you start talking, some spit can get on the coin. This causes spots on the coin over time. Many Mint-State and Proof coins have been ruined this way.

Expose to Acid or PVC
Exposure to either acid or PVC can cause damage to the coin. Both can cause spotting, discoloration, or ugly toning.

Expose to Extreme Temperatures
Coins in certain filps (2X2's) can be damage by either too hot temperatures or too cold temperatures. Make sure your coins are in a temperature-controlled safe or somewhere else where the temperature does not change.
