Dusted the cobwebs off the Metal Detector today and went down to the riverbank with Mellons. It's a tidal river so waited for low tide then picked a nice spot downstream and got fishing in the dirt! Second signal was this wicked ring with an Eagle head. I thought it was Copper or Brass but after cleaning I can see a 925 hallmark just visible next to my thumb! Not seen Silver this colour but it could be an odd patina from the mucky shoreline silt. It's a nice ring and fits me well so might try and clean it up, or just keep it on my finger and see how it changes with a bit of natural wear and tare. Keep you posted :-)
