Think your rare coins look a little "dirty"? STOP! Before you reach for the polish or baking soda, watch this video.
In this Coin Conservation Masterclass, we dive deep into why amateur cleaning is the #1 value-killer in the numismatic world. We explain the science of mint luster, why "hairlines" are a permanent scar, and how top grading services like PCGS and NGC view cleaned coins.
In this video, you will learn:
The "90% Rule": How much value you lose the moment you clean a coin.
The Cartwheel Effect: The science behind original mint luster.
Cleaning vs. Conservation: When it’s safe to seek professional help (NCS/PCGS).
Proper Handling: Why you should never touch the "fields" of a coin.
Storage Safely: Avoiding the dreaded "PVC Slime."
Disclaimer: This video is for educational purposes. Always consult with a professional numismatist or grading service before attempting to alter any rare or valuable coin.
