How to sell a rare coin
If, after checking, you realise you've come across a rare coin, there's a number of ways you can sell it.
You can sell it on eBay, through Facebook, or in an auction.
But be wary of the risks.
For example, there are a number of scams targeting sellers on Facebook.
Crooks will say they're planning to buy the item and ask for money upfront for a courier they'll be sending around.
But it's all a ruse to get you to send free cash to them - and they never have any intention of picking your item up.
It's always best to meet in person when buying or selling on Facebook Marketplace.
Ensure it's a public meeting spot that's in a well-lit area.
Avoid payment links and log in directly through the payment method's website.
Most sellers prefer to deal with cash directly when meeting to ensure it's legitimate.
The safest way to sell a rare coin is more than likely at auction.
You can organise this with The Royal Mint's Collectors Service. It has a team of experts who can help you authenticate and value your coin.
You can get in touch via email and a member of the valuation team will get back to you.
You will be charged for the service, though - the cost varies depending on the size of your collection.
Meanwhile, you can sell rare coins on eBay.
But take into account that if you manage to sell your item then eBay will charge you 10% of the money you made - this includes postage and packaging.

Always keep proof of postage to protect yourself from dodgy buyers who may claim they never received the item.
Send the parcel by tracked delivery if you can as this way they can't claim it never arrived.

2002 Commonwealth Games England - £35
Another in the 2002 Commonwealth series, the English version is one of the rarest coins in circulation.
Some 650,500 were minted at the time, making the coin rare enough for eBay bidders to happily pay as much as £35 for it.

The coin wasn't always considered so rare, but it has since transpired its mintage figure was incorrectly published.
A recent auction on eBay saw the piece go for £14.95 with one bid.
