The ultimate answer is priceless due to the fact you get three free wishes if you acquire the glorious gold of the Lucky Leprechaun. However let us assume you’re quite nuts, and refuse to give back the pot of gold for the wishes. Say you cash it in instead like a complete fool idiot. A Leprechauns pot o’ gold generally contains 1000 one ounce pure gold coins. At the current January 2017 gold rate of $1165 per ounce that makes a pot of gold worth $1,165,000.
Consider the fact that you passed over wishing for a billion dollars, or more, for this paltry $1.165 million. Or wishing for a plethora of other things that money might not be able to buy such as immortality. A pot of golds real worth are it’s priceless wishes. The gold is the source of a Leprechaun’s supernatural power, and if you do cash it in he will most likely hound you for all the rest of your days. The little lucky fellows can hold a grudge when they feel cheated, and they can get downright ornery!
You can also get those same wishes without finding the gold hidden at the end of an elusive rainbow by simply capturing the Leprechaun. Using high quality Shamrock as bait is the best method. Just be careful in your capture, and holding method so there’s no hard feelings after the wishes are granted. Also remember that Leprechaun wishes aren’t like Genies wishes. Leprechauns wishes are based on good luck imbued upon you. After that you have to do the rest so all wishes aren’t possible. So you can’t wish for world peace but you can get a billion dollars by winning lotteries, gambling, playing the stock market, etc. As for immortality there can be a number of methods in which you would stumble into it such as being injected with top secret cellular regeneration nanobots from the future, or having a powerful practitioner of magic imbue you with an eternity of youth. With good luck on your side you will win every time!
