Best Way to Preserve Old Germa...

I have some old 1 Pfennig German coins that I want to keep in good shape, but I’m not sure about the best way to store them. I’ve read that some materials can damage coins over time, and I don’t want to accidentally ruin them. Should I keep them in plastic cases, paper envelopes, or something else? Also, does cleaning them affect their value?

Cleaning coins can actually reduce their value, especially if they’re collectibles. Even light cleaning can leave scratches that lower their grade. If you want to check the worth of your 1 Pfennig coins before doing anything, a good resource is https://coinstrail.com/catalog/germany/brd/circulating-1-pfennig/63527004c80828517e998419 It provides valuation details based on condition, so you’ll know whether your coins are worth keeping as-is. As for storage, the best method is using acid-free coin flips or airtight capsules to prevent oxidation. Avoid PVC plastic, as it can cause damage over time. If you have high-value coins, consider storing them in a cool, dry place away from direct sunlight.
