I found a fork in an old creek bed. Thought it was silver but seems to leave gold on the slate. Did a comparison with pure silver and seems to be solid silver/gold. No idea how old it could be - cant make out the stamps - was totally covered in iron oxide so had been laying in the ground for decades.
Found a 1907 threepence also in the same creek so gives some idea of timeframe of the area.
Unreal whats out there. The big fork is just a steel fork for size and colour comparison. Im gonna shine it up when i get back to society
