kac Posted February 23, 2021 Share Posted February 23, 2021 So would that be close to a nickel? Link to comment Share on other sites More sharing options...

Aren't some modern Canadian coins made of pure nickel? What dTID do those indicate (anyone)?  1 Link to comment Share on other sites More sharing options...
kac Posted February 23, 2021 Share Posted February 23, 2021 Some Canadian coins are also steel so it could be one of those. Link to comment Share on other sites More sharing options...

I wasn't thinking that since cuniagau's photos show features consistent with an early USA dollar. I just was wondering what dTID a pure nickel coin would indicate. -7 to -8 sounds low for that, but since I've never found one I don't know -- making me curious. (Frankly if you had asked "what dTID do you think this object would read if it is iron or iron alloy?" I would have guessed much higher than -7 or -8. Shows what I know....) There aren't many ferromagnetic elements or even alloys, but this certainly gives strong evidence it is made of one! It's just weird (to me) that someone would make a replica or counterfeit out of iron or iron alloy. Copper and its alloys are such a reasonable alternative (but it's obviously not that). By the same argument, pure nickel or some other ferromagnetic metal doesn't make much sense to me, either. Still a mystery as to its origin and purpose, AFAIC. We detectorists sure are good at finding these mysterious objects. 2 Link to comment Share on other sites More sharing options...
kac Posted February 23, 2021 Share Posted February 23, 2021 Low grade stainless steel alloys should have low tid's. Might be other countries that use steel. Copper/nickel alloys will ring in higher but think maybe pure nickel would be too tough to strike? Link to comment Share on other sites More sharing options...
