the coin isn’t worth compromising your safety.
What If You Find a Large Amount of Money?
That’s different from finding a single coin.
If you discover a wallet, envelope, large amount of cash, or identifiable property, don’t simply assume it is yours.
Depending on where you live, there may be legal or ethical obligations regarding lost property.
A wallet may contain:
Identification
Bank cards
Personal documents
Contact information
In such cases, turning it over to the appropriate authority or making a reasonable effort to return it is the responsible choice.
