This could really perk up your Christmas fund...
Sorry in advance if this makes you feel old but we haven't used pound here in almost 20 years.
On 9th February 2002, the Irish pound was no longer legal tender, so we all had euros from then on.
While it is a while ago, it's not unheard of for people to come across some old money in the house.
Especially if you've been to the UK recently, it's likely you'll have some pound in nooks around the house, old purses, wallets or pockets.
We'd recommend, you spend some time looking because apparently they fetch a fair sum these days.
The Sun reports that some old £5 notes in particular have been sold online for much more than their value.
One even got almost £300!
Where's all this happening? - eBay of course.
The paper scoured eBay and found one older £5 note which managed to fetch almost £300.
Don't believe us? Well, take a look:
Apparently it's "great for serial fans as it has 111111 printed on the design."
It sold on eBay on October 30 for £298 after 20 bids were placed on it.
It was described as being in "excellent" condition.
Another find is that notes with no signature are well-sought after.
One such £5 note without a signature sold for £266.05.
Another big seller was a 1957 £5 note which sold to the winning bidder for £113.11.
So, whatcha waiting for? Time to turn the house upside-down in search of your treasure.
