Rainy weather resulted in my exhausting after 2 hours - my weight became 20 kg higher every 10 minutes because of dirt attached to shoes. Few finds are here -
Ni-Cu 5 pfennig coin - colour is a result of selective corrosion - Ni is away faster_ and Cu gives that colour
Can't say much - coin is made of Zn_ date is 19??, country is unknown yet.
Best of the day - coin weight from ~1800s from Johann Caspar Mittelstenscheidt.
Thanks for viewing and HH
