Pennies, Nickels, Quarters, Dimes...
If a penny is copper, and a quarter is silver, what color is a nickle?
And a lot of copper at that. It currently costs $0.0102~ to make each penny. I could imagine how much the heavy nickle costs considering it is mostly copper. Kinda surprised it dosn't have zinc in it too.

75% Cu
ReplyDelete25% Ni
Kinda like a sandwich material. Really just a copper coin with a nickel outside. Like a candybar with nougat.
was that really a brain buster?
ReplyDeleteI think Mr. karnov missed this one.
ReplyDeleteA penny (currently minted) is copper - on the outside and zinc ont he inside, but still it is copper colored.
A quarter is also a sandwiched coin with a silver/tin alloy on its surface, or the color of silver. The same for a dime.
A nickle is nickle colored. I did not know that it had copper in its core, which seems counter-intuitive with the cost of copper.

ReplyDeleteI guess it was a brain buster.
ReplyDeleteThe N-I-C-K-L-E is a green woodpecker. The coin is spelled N-I-C-K-E-L.
Excuse me while I gloat for a minute. I actually got you all! :-)

OK, minutes over.
I noticed the misspelling, but was too busy yesterday to think further about it. But now I'm on to your little game...
ReplyDeleteMike---good one :)
ReplyDeleteEnjoy your victory...this is the first one I saw that stumped everyone and wasn't actually confusing or incorrect :)
DOH!
ReplyDeleteI didn't think the spelling mistake was on purpose... i figured you just transposed the e and l when typing too fast.
ReplyDeleteA nickel is nickel colored though.. at least on the outside... unless of course you scrape all the Ni off of it.
