I found an incredibly old object of great value once. So rare that it would have been desired by a government authority.
Only showed it to a handful of close family and enjoyed it for 30 years before donating it to a worthy institution.
Do you have any idea what it costs to be an expert these days?!

Don’t know the situation in Germany. In Britain found treasure is ‘treasure trove’ and property of the Crown. But the Brits are smart in that regard. They pay fair market value for whatever the Crown (usually museums, etc.) want to keep. The finder gets paid and whatever coins or treasure aren’t interested in. That way, people aren’t encouraged to keep such finds to themselves and the finds are able to be studied scientifically by experts.
