While rare 50p coins often have sky-high asking prices on eBay, that doesn’t mean you’ll actually get that much. We asked the experts what collectors will really pay for the most valuable 50p coins still in circulation.

A rare 50p coin may have sold for more than £90 on eBay earlier this week.

Special edition Team GB 50p. Ahead of the 2016 Olympics in Rio, the Royal Mint issued a special 50p to celebrate Team GB. Around 6.4m were released into circulation, making it much more common than any of the Olympic series coins. But if you’re seeking to complete your Olympic collection, you may wish to hunt down one of these. Stay tuned for the 50p Coin Hunt tomorrow on New Years Day at 3pm. I found an Olympic 50p Coin and much more Please Subscribe and hit that notification bell.

A listing for a Kew Gardens 50p coin achieved a winning bid of £91 (thanks to the Mail for spotting this) on 30 May.

You may have noticed that we said the coin 'may' have sold rather than 'has' sold.

As we've reported before, we've sadly seen a number of confirmed sales fall through on the auction site in the past, so we'll have to wait for confirmation of a successful sale.

That's not to say the coin in question isn't valuable and couldn't fetch such a price.

As you'll see below, genuine rare 50p coins have already been known to sell for £70.

So how can you tell whether your 50p piece is actually worth more than its face value? Read on to find out.

Don’t believe the hype

Be wary of both tabloid articles and asking prices online, says Luke Hearn of the Change Checker website.

Both can give a very over-inflated idea of what a coin is really worth.

'To be honest, there is a lot of misinformation written in the press regarding coins,' he says.

'The first and most obvious example of this is when people list coins for a ridiculous amount on eBay when actually nobody is ever going to pay that much.

“I think the reason behind this is nothing more complicated than people chancing their arm on the off chance they may get lucky.'

It's best, then, not to be too optimistic – and, if you're checking prices out on eBay, make sure you look at the prices coins have actually sold for, rather than the asking price.

Still have some of the old £1 coins? Find out if they are worth more than face value

What collectors are looking for

If you do find a rare coin, it'll need to be in good condition with little sign of wear and tear if you're to get any more than the face value.

Collectors are particularly keen on ‘Brilliant Uncirculated’ coins, which are made with a special superior finish.

However, it's still worth checking your change for 50p coins that were never intended for circulation but somehow have slipped out.

'This sometimes happens when some poor soul is robbed of their coin collection and the thieves simply break them out of their packaging and spend them,' says Perkins.

'Some of these coins are valuable: for example, the 2011 Olympic Aquatics coin with extra lines on the swimmer's face, which was a design that was withdrawn, not adopted and shouldn't have seen the light of day.

“They are rarely offered for sale as they are rarely encountered. The withdrawn 50p in its original packaging is worth £1000-plus.'

But it’s not all about the super-rare coins. There are many for more common 50p versions that are worth a few quid to collectors.

So if you've got a spare couple of minutes, you may want to fetch your purse or wallet right now.

Check Your Change has put together a list for loveMONEY of some of the 50p pieces in circulation that are genuinely worth more than their face value.

Happy hunting!

The 2009 Kew Gardens 50p: up to £70*

The Kew Gardens 50p was released in 2009 to celebrate the 250th Anniversary of the Royal Botanic Gardens. It's the rarest coin of any denomination currently in circulation, with only 210,000 ever issued.

*Pending confirmation

The 2011 Olympic Football 50p: around £8

Of the 29 50p coins issued to mark the 2012 Olympics, the Football version is the most valuable.

The 2016 Puddle-Duck 50p: £6 – £8

The Jemima Puddle-Duck 50p is the rarest of the five coins in the Beatrix Potter series. Only 2.1 million are in circulation.

The 2011 Olympic Triathlon 50p: around £6

Olympic 50p Value List

There are 2.18 million of these in circulation, depicting a runner, a cyclist and a swimmer.

Olympic 50p List

The 2011 Olympic Judo 50p: around £6

With 1.16 million in circulation, this is one of the rarer Olympic coins.

The 2011 Olympic Wrestling 50p: around £5

Designed by Roderick Enriquez, this shows two wrestlers in action.

Other Olympic coins

In fact, all of the 2011-dated Olympic coins are harder to find now and can find buyers for between £1 and £2.

But, says Perkins, 'Obviously if you take selling fees into account and the hassle of posting them, it's a lot of effort to make £1 or so!'

The 2003 Suffragette 50p: around £1.50

This is worth three times its face value.

The 2011 WWF 50p: around £1.50

Again, this 50p is only just about worth selling, once you've taken fees and postage into account.

The Olympic sports 50p series was a revelation in coin collecting – for many it represents the start of their interest in UK circulation coins and thousands rose to the challenge of finding them all from their change.

But the mintage of each coin in the 29-piece collection is different, and so the likelihood of finding one varies accordingly. Football narrowly holds the title of the rarest sport in the series, but there were still over one million of those struck for circulation. A coin with such a high mintage can hardly be considered as “rare”. For that honourable title, we must look beyond the official Royal Mint circulation figures…

Olympic 50p Set

The original Aquatics Olympic 50p

In September last year, we reported on an Aquatics 50p which sold on eBay for £820. As you might suspect, it wasn’t an ordinary Olympic 50p which we would typically pull out of our change – it has a very specific minting ‘error’.

The design was modified to make the swimmer more visible.

Olympic 50p Swimming

The Aquatics 50p which we are familiar with today is actually a modified version which removed the waves passing over the swimmer’s face. However, a small number of the original design were produced before being modified, although this quantity remains a mystery.

What we do know is that it is not unusual for these special coins to exchange hands for close to £1,000 – not a bad return on a 50 pence coin!

Olympic 50p Rare

The 2009 Athletics Olympic 50p

In 2009, nine-year old Florence Jackson became the youngest person to design a coin for circulation in the UK. Her Athletics Olympic 50p design was the ultimate winner of a Blue Peter competition and her creation featuring an athlete midway through a high-jump can be now be found in our change up and down the country.

You probably recognise the coin, but what you may not know is that a rare version of this coin exists. When the competition winner was revealed, a special edition Blue Peter presentation pack was issued with a 2009 dated coin, making it the only Olympic 50p without a 2011 date. Just 100,000 of these packs were issued, meaning it is more than twice as rare as the famous Kew Gardens 50p.

A gold version of each design was presented to the respective artist

The winner’s gold editions

But rarest of all are the gold versions of each 50p which were presented to their respective winning designers. Only one of each design exists. You certainly won’t find one of those in your change, and they will be quite literally gold dust for years to come.

Aside from their precious metal content, their unique status and significance rank them as potentially the most valuableUK 50p coins in existence.
