My pleasure. You are welcome.
That tricky and toxic mercury can make brass brittle.
The 110 dated 1995 dates the knife in the river. I used pennies showing the year that the river was mined. When we put the river/stream back together, after removing everything in order to get the gold that was on the bedrock, we would leave a penny to date our mining activity for the next miners to work it. BTW, we put the river/stream back better than we found it with fish and fisherman in mind as we all love nature and fishing and took pride in our work.
Sidebar: A fellow who lived alone on a claim up on the Josephine found a large old glass jar 2/3 full of mercury in the crouch of a tree. I tried to buy it but he wouldn't sell unless I also paid for any gold that might have been in the amalgam. The jar was very very heavy. I wondered how it had survived over the many years without being discovered or broken. Still think about the fellow, who taught my young boys to snipe for gold with very little gear, rest in peace.
