Coins celebrating the Queen's Sapphire Jubilee have flown off the shelves at the Royal Mint so quickly that they are set to become valuable collectors' items. They include a £5 coin struck to celebrate the Queen's 65 years on the throne. So can you make money from the coin?

There are a few versions of the £5 coin. There's the standard one - an uncirculated proof in a commemorative pack that will set you back £13. There are plenty of these still available, but these aren't the ones that collectors have their eyes on.
Along with the straightforward coins, the Royal Mint produces a number of very limited edition versions in a variety of metals - and in specific runs. A number of these have sold out already.
Of the £5 coins, there were 8,000 sterling silver proof coins produced at £82.50, and they have all sold out at the Royal Mint. Coin sellers are now selling them on for between £95, and £130. As their stocks run low, we can expect this price to climb.
There were also 2,500 Silver Proof Piedford Coins priced at £155. These have sold out too - and are now changing hands for £300 or more.
And there were Gold Proof Coins. Just 650 of these were struck, and they sold out at £1,945. They have been priced up to as much as £3,000 by dealers.
More in the set
It's not just the £5 coins in the set that have sold well. There are also £10 coins - with a different design on the reverse. There were 1,500 five-ounce silver proof coins produced, priced at £415, and these have sold out too. They are being sold on for £495 at the moment. The five-ounce gold proof coin, meanwhile, cost a whopping £8,250, and all 110 of them have sold out.
There are Sovereigns too. There were 750 22 carat gold Sovereigns struck on the day of the Jubilee on 6th February, and priced at £500. These have all been reserved.
Then there's a £500 coin. There were 250 silver proof kilo coins made - of which 85% have sold. One of these would set you back £2,050.
And there's a £1,000 coin - a UK gold proof kilo coin - priced at £49,995.
Why are they so collectible?
The Royal Mint has hit on a winner, because this is the first ever Sapphire Jubilee in British Royal History. Given the longevity of Royals nowadays, there's unlikely to be anyone crowned much before the age of 60 in future - so another Sapphire Jubilee is hardly on the cards.
It has also created demand from scarcity - with a handful of some coins made. The fact that so many have sold out - and that so many dealers have hiked the prices - is an indication that short term buying and selling has made some people plenty of cash.
Of course, as always with coins, there's no guarantee that their price will rise, and that you will get back what you paid for it - let alone more. As for £5 coins, because they are not in circulation, you can't even spend them to get £5 of value from them.
Whether or not you buy one, therefore, depends on how much you would get out of owning one, and whether you can afford to lose the money you spend. So what do you think? Are they worth it?
