THE most valuable McDonald's toys ever have been revealed by an antiques website and a toy expert.

If you find a set of TY’s Teenie Beanie Boos (from 2000) - you could be sitting on £338.

Plus, there are loads more McDonald’s toys that are each worth a small fortune.

Who made the list?

Antique website LoveAntiques.com created the list with toy expert Peter Jenkinson, with a set of guidelines for prospective toy collectors.

The guidelines include information on the condition toys must be in to command the highest prices.

Jenkinson highlights how certain aspects can alter the value dramatically, with the packaging and the condition of the toy ultimately impacting selling price.

He advises all potential collectors to buy and keep toys in their original packaging/bag.

The guidelines also advise long term investors to buy toys two at a time, so collectors have the choice to open one and keep the other.

Also, collecting full sets of toys results in a bigger sum than collecting individually.

Jenkinson recommends collecting popular, limited edition toys too, such as LEGO sets which are linked to films and franchises.

“There have been thousands of McDonald’s happy meal toys over the years and knowing which ones are just a piece of plastic or which are worth something, is always a struggle," says Jenkinson.

"This list is forever growing so if you think you might have something valuable, try and get hold of as many of the toys in the set as possible and keep hold of them.

"Also check your old ones too, if you have any lying around in the attic or an unused draw, get them looked at – you could be looking at a healthy sum, especially if you have one on the list I’ve put together.”

Will Thomas managing director at LoveAntiques.com said: “Toys are a hugely popular area for people to invest in, but we’ve never realised just how much people could get for their old McDonald’s toys.

"It’s interesting to see just how much a once free plastic toy can be worth, and how much money people might have, unbeknown to them, just lying in their attic or drawers.”
