"If you've ever had one of these popular childhood toys it might be time to get in the attic and dig them out - you could make a substantial profit."

Classic toys could now be worth nearly $4k

BARBIE, Hot Wheels and Polly Pocket are just some of the classic childhood toys that are now worth a small fortune.

You might want to head into your loft and dust off your old toy box as The Sun reveals how retro playthings can fetch you just under $A4000.

The most valuable old school toy based on its appreciation in value, according to new research by Liberty Games, are Hot Wheels cars from 1968.

Costing 90 cents back in the day, one car was being sold on eBay with a "Buy it now" price of $A809.07 - an increase of about 90,000 per cent.

The games room specialists also noted a Barbie from 1959, originally worth $A4.53, fetched $A1132.15 on the auction site - up by nearly 25,000 per cent.

The next toy with the highest value increase was a Cabbage Patch Kids doll from 1978. First priced at $A37.79, it sold for $A3930.02 - an increase of more than 10,000 per cent.

While these are just some examples of what these toys could sell for, there's no guarantee you'll make the same amount if you sell a similar product.

And if you're pricing your own toys on eBay, you're better off using sold prices as an indicator of what you can get as "buy it now" listings don't necessarily always sell.

It's worth noting that rarer items, or ones that are limited edition, are often worth more.

"Many of the toys are still being sold today, with original Barbie dolls, Monopoly boards and Teenage Mutant Ninja dolls worth up to thousands of pounds to collectors," Liberty Games technical director Stuart Kerr said.

"If you've ever had one of these popular childhood toys it might be time to get in the attic and dig them out - you could make a substantial profit."
