How to Preserve Maximum Value
Handle by the edges only – Fingerprints can cause rapid toning
Store properly – Use airtight capsules, anti-tarnish strips, and a climate-controlled environment
Never clean your coins – Even plain water can ruin surfaces
Where to Find “Red Gem” Pennies
- Original mint rolls from the year of issue
- Estate collections stored in dry, stable conditions
- Bank bags from the 1950s–60s
- Old albums with coins untouched for decades
