1992 South African Rand Are these cupronickel?[ATTACH] [ATTACH]
Thanks for the info. I have two handfulls of lead weights from the roadside. Maybe I'll melt them down for free (with the sun) to make an ingot.
One day I hit a penny with metal polish a few too many times, and it wore off 10% of the copper showing the zinc below. Looked like crap.
Tungsten die, and heat up the SS blank? I'm thinking inconel, and use heat on the SS blank. Inconel maintains it's strength at high temperatures...
With post-covid inflation, it looks like stainless is the only metal we can use to make a nickel cheaper than its melt value. It was 7.5 cents at...
Good point. Sport bikes have stainless brake rotors, tougher than nails. (Mild stainless, probably only 5% to 7% chromium.)
My favorite is only my favorite because it didn't have much corrosion despite being in circulation for thirty or forty years. In fact, the 1954...
Because copper turns brown then green, silver turns milky white then black, cupronickel turns a darker grey, and bronze/brass even turns weird...

I change my prediction on the nickel. I think it'll keep it's size, but be made of stainless steel. There are many versions of it, t's as cheap...
Big Brother and George Orwell would love this. We are already being cancelled at the whims of the government, colleges and corporations.
Me too!
Pretty sure they put an abrasive in the water, such as sand. That's why I recommend ultrasound. It uses clean water.
By this definition a coin that was in circulation for decades or centuries has been tooled and altered by normal wear and corrosion, much more...
When It' using a brush or cloth it's that dirt that you push around that scratches metal or glass. Paper doesn't even scratch glass like they...
Remember that coin shortage last Summer? Yeah, somebody was anticipating this surge in commodities prices and started hoarding coins. And toilet...
Now I need one of those. Jamaica has UK currency, right? Going to Jamaica...
Thanks for the offer, Saxon. I'll trade you a proof set of US coins if you can find me some undamaged versions of these six UK coins.
Cool. I'm going to Bermuda to get some. Or my biggest local bank.
Do we have to go back in time to before decimalisation to find all these UK coins that form the coat of arms? Or is this coin puzzle even true?
