Coins become dark when time passes..How to keep them shining for long? Especially silver and coppper coins become dark.
thanks for the tip..It would be really helpful to keep my coins safe. I did not know about a light coating of CoinCare before.I will try itNothing is 100% foolproof. Best methods are low humidity storage using acid free albums/containers. In other than ideal conditions, I'd use something like a light coating of CoinCare or similar.
