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. Instead you cash it in like a complete fool idiot. A Leprechaun’s pot o’ gold generally contains 1000 one ounce pure gold coins. At the current October 2017 gold rate of $1,290 per ounce that makes a pot of gold worth $1,290,000.
Consider the fact that you passed over wishing for a billion dollars, or more, for this paltry $1.290 million. Not to mention wishing for a plethora of other things that money might not be able to buy. Fantastical things such as immortality! The real worth of a pot of gold is its 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! They can get downright ornery, and could possibly impart bad luck upon you!
You can also get those same wondrous 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 containment method so there’s no hard feelings after the wishes are granted. Also remember that Leprechaun wishes aren’t like Genie wishes. Leprechaun wishes are based on good luck imbued upon you. After that you have to put in some effort, and let good fortune take its coincidental course. 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 courtesy of a time traveler, or perhaps a top secret government project. You could be lucky enough to find a powerful practitioner of magic to imbue you with an eternity of youth. You may also wish for love, and it will find you. However you must at least leave the house every so often. With good luck on your side you will win every time!
