Crazy Coin
I am 200% of a penny, 25% nickel, 118.4% of a dime, 111.4% of a quarter, and 10% of a half dollar. What am I?
HintI have been around for 64 years.

Answer
The answer is a Jefferson nickel or 5 cent piece. A nickel weighs 5 grams while a penny (Lincoln cent) weighs 2.5 grams, so it is 200% the weight of a penny. A nickel's diameter is 0.835 inches (21.21mm) while a Roosevelt dime's diameter is only 0.705 inches (17.91mm), so it is ~118.4% of a dime's diameter. A nickel has a thickness of 1.95mm and the Washington quarter is only 1.75mm thick, so the nickel is ~111.4% of a quarter's thickness. The monetary value of a nickel is 10% of a Kennedy half dollar (5 cents/50cents = 10%) and a nickel is composed of 25% nickel (the metal nickel, Ni). The other 75% of a nickel made of copper.

| Hey everyone, I was just wondering, did anyone solve this one? Did I make it too hard? Should I have added some other clues to make it more solvable? Sorry if it seems unfairly hard. :-( |

| Yes, I think it was too hard. It would be
one thing if all the percentages were
based on a common feature or measure,
but having them all on different scales
(and most of them rather obscure)
makes it hard to discern the pattern.
I did a web search based on the hint
to find out what happened in 1938, found
the specified answer, and couldn't see how it fit
the problem. |

| Let me say first that you have to put effort into a teaser like that. Therefore only with effort can a person dissect and solve it. I, myself did not put in the effort, so I can't complain. Neither should you. There is no such thing as "too hard" of a teaser. That's why they are called BRAIN teasers. Accept you limitations sometimes, and say "too hard FOR YOU" rather than just "too hard." Besides, "If it can be conceived by man, it can be conquered by man." |

| I had the basic idea behind it but we non-Americans simply don't know enough about you coins. When you said 200% of a penny I figured that maybe there is some coin called "2 bits" or something. It was an interesting idea but without some coins to at least measure, I would have to do too much research to finish it. |

| I think I would've understanded the answer if I was American. Facinating teaser though! |
