Imagine there are 3 coins on the table. Gold, silver and copper. If you say a truthful sentence, you will get one coin. If you say a false sentence, you get nothing. Which sentence can guarantee gaining the gold coin?
I WANT THE GOLD COIN :TRUTH = GETTING COIN
I WANT THE GOLD COIN :LIE =NO COIN
EITHER WAY YOU GET WHAT YOU WANT

Assuming that you're responding to JASON4P8C10's post above yours:

You couldn't receive one coin, as that would mean you are receiving a coin for uttering a false sentence which breaks a condition of the riddle. If you say, "I will not get any coins", you have put the coin giver in a paradoxical situation.

The problem doesn't mention that anyone is around. I would just keep my mouth shut, pick up and pocket all three coins.

That would REALLY be a paradox!

Assume you said "I will not get any coins".

If you then get any coin, you have been lying, and therefor deserve no coin. But not getting a coin would mean you told the truth and thus deserve to get a coin. Which brings you back to getting a coin for a lie, and so on, and so forth, ad infinitum.

But I've thought of two possible ideas:

1: Say "You won't give me anything but the gold coin".
-----------------------------------------------------
Now, IF they give you anything but the gold coin, you would have lied, and therefor deserve no coin at all.
And if they give you no coin at all, you had been saying the truth and thus deserved a coin.
The only way they can avoid paradox, is by giving you the gold coin.

2: Say "IF you give me ANY coin, it can ONLY be the gold one".
-------------------------------------------------------------
This is actually the same statement in a somewhat different form. Thus it would result in exactly the same situation as above: they can ONLY give you the gold coin to avoid a conflict of terms.


Happy puzzling,
