Hundreds of classic children's toys are being auctioned on eBay for asking prices comparable to your average car. 

Pokémon trading cards are selling for thousands, with the top asking price for a single card listed as £1,650, while the Princess Diana Beanie Baby is valued at up to £65,000.

eBay sellers are demanding extortionate amounts for old children's toys. The Princess Diana Beanie Baby, which experts value at a maximum of £40, is being listed for as much as £65,000

Similarly other pocket money buys like Lego figures, with an average retail price of £2, are listed as high as £2,187 for a Star Wars Boba Fett edition.

We were all told as children that one day our TY Beanie Babies would be worth a lot more than their original £4.99 price tag. 

Single Pokemon cards have asking prices higher than a meal for two at a restaurant with a Charizard edition for £41 achieving seven bids

While the majority of them are worth little over £1 on the auction site, The Princess Diana Beanie Baby, which was introduced in October 1997, is currently considered somewhat more valuable.

It is considered highly collectible after TY informed US retailers that it could only order 12 of the bears to be stocked in their stores following the launch.

The TY Collector currently has the highest valuation listed as £40 ($63) but that hasn't stopped eBay sellers asking for as much as £65,000 for a single bear (over $100,000).

People seem to be showing interest in these sky high prices, which could buy you a small property, with that particular listing attracting 12 watchers.

Another enterprising US seller is auctioning their Barbie doll for $16,400 (£10, 500).

The original Barbie, which was released in 1959, has attracted 140 interested watchers - despite the fact she is being offered without clothes or her original packaging.

A first-edition Barbie, listed in the US, without clothing or packaging, has attracted the attention of 141 watchers and has an asking price of $16,400 (£10,500)

Peter Jenkinson, a toy expert told BT that it was the nostalgic nature of the toys that pushed their prices sky high. 

He said: 'The look and feel of things we owned as kids, or which we wanted to own but never could, lets us tap into happy memories and allows the big kid in us all to thrive.'

Peter added that customers of all ages are willing to fork out extra for an older or original model of their favourite toy.  

'There's also the notion that things were "better before", whether that's in the manufacturing quality or more in general, this romanticised image of the past can be brought to life with cool, retro toys.

'It might be parents rediscovering classics with their own kids or hipster types giving their trendy selves an even cooler edge with a retro toy accessory, the point is that nostalgia is king.'
