How Coins Get Damaged After You Buy Them (The Hidden Enemies)
You bought a perfect coin. You put it in a drawer. Five years later, it is ruined. Here is what happened.
Nature hates shiny metal. Nature wants to turn silver back into silver sulfide (black tarnish). Your job is to fight Nature.
Enemy #1: Moisture (Tarnish)
Humidity is the killer. If you live in Florida and store coins in a cardboard box in the garage, they will turn black. Fix: Silica Gel Packs inside an airtight ammo can.
Enemy #2: PVC (Green Slime)
In the 1970s, people used "soft" plastic flips. They contained Polyvinyl Chloride (PVC). Over time, PVC leaches a green, sticky acid that eats the metal. Fix: Only use "Mylar" or "SAFLIP" (rigid) flips. If your flip smells like a shower curtain, THROW IT AWAY.
Enemy #3: Friction (Bag Marks)
If you put loose coins in a bag and shake them, they scratch each other. Fix: Plastic Tubes. They lock the coins in place so they can't rub.
