Coin Price Details and Risk Factors
Rare coin investment requires a good understanding of metal damage processes. Many new coin collectors make bad mistakes that destroy coin value.
Mechanical Coin Cleaning
An attempt to clean a coin with friction is a giant mistake. Using toothpaste, soda, or hard fabric leaves many tiny scratches on the metal.
This action removes the original mint luster immediately. A cleaned coin loses at least seventy percent of its market value. Professional grading companies will not give a standard numeric score to cleaned coins.
These companies return coins in a details holder, making them very hard to sell.
Chemical Metal Degradation
Bad storage conditions start chemical reactions on coin surfaces. Using cheap plastic coin albums is a major risk factor. These cheap sheets often release bad plastic chemicals over time. This chemical reaction creates a sticky green oil on silver and copper coins.
This green substance slowly eats the metal, creating deep holes. The value of a coin with bad plastic damage drops by ninety percent. You must use safe hard plastic holders to protect your coin collection.
Real Price Loss Examples
A Philippine coin collector bought a rare 1906-S peso in Extremely Fine condition for $12000.
He decided to remove the dark natural color to make the coin shiny using strong house chemicals. This chemical cleaning made the coin surface look dull and gray.
Professional dealers valued this ruined coin at only $3000 during a resale attempt. This simple cleaning action caused a $9000 financial loss.
Another sad case happened with a silver 1903 coin set stored in a wet basement without protection. The coins developed thick black corrosion deep inside the silver metal. The set value dropped from $2500 to a basic silver melt value of $120.
Practical Investor Tips
Buy only coins certified by professional coin grading services. A plastic coin holder with a certified grade guarantees authenticity and helps future coin sales.
Never buy rare coins from unverified online sellers. The coin market has many fake 1906 pesos from illegal factories. Focus your attention on mid-range coins in high grades instead of super rare items.
Twenty and fifty centavos coins minted before 1907 offer the best value growth potential. These coin prices rise faster than regular inflation, protecting your money.
Keep your coin investments for at least five years. The coin market rewards patient collectors with great financial profits.
