this one is ridiculously obvious, and because of that, some people totally miss it. :smile:

you have two coins, and the sum of the value of these two coins is $.15

(they are american coins. no japanese coins)

if one of your coins is not a nickel, what are the value's of your coins?

(maybe asking this is a math forum is a mistake, but hey w/e maybe ill embarrass someone :) )

This isn't really a math problem at all. Probably why I know the answer.
One is a nickel. The other is not a nickel. It is a dime. :smile:

Whited Out--> Only one is not a nickel, the other one can be, so one's a dime, the other's a nickel. :wink:
That's too obvious
 
Wow! There are a lot of answers to this one... Uhmm... here are a couple:

Coin#1 : PCGS#83380 CA design from 1957 with a PCGS grading of 60. Penny worth 14 cents.
Coin#2 : PCGS#3184 RD design from 2004 with a PCGS grading of 65. Penny worth 1 cent.

Coin#1 : PCGS#83374 CA design from 1955 with a PCGS grading of 60. Penny worth 7 cents.
Coin#2 : PCGS#3107 RD design from 1993 with a PCGS grading of 65. Penny worth 8 cents.

Coin#1 : PCGS#93437 DC design from 1972-S with a PCGS grading of 65. Penny worth 11 cents.
Coin#2 : PCGS#83389 CA design from 1960 Large Date with a PCGS grading of 60. Penny worth 4 cents.

Any of these would work, since you're asking the value and not the face value. Wow... that's a pretty complicated question with a lot of answers.
 
My puzzle starts with knowing the value of a nickel. No sir, I am not speaking of economic value :rolleyes:

It doesn't say face value, so it's open to any value I guess. I'm just trying to be creative.
 
Yes, this is a classic example of overthinking by most people...

ONE of the coins is not a nickel...

thats right because its a dime...
the other coin is a nickel...
 
lol yes you probably could go on funny coins... but as I said nothing weird :) i guess you missed that :smile:

anyway its easy but you would be surprised how many people miss it and then respectively miss you with a hammer after they hear the answer
