These football stickers are being sold for a small fortune - and if you own any you could be sitting on a major score.
One of the priciest stickers around is of Brazilian legend Ronaldo, from his time at PSV Eindhoven, where he was managed by ex-England manager Sir Bobby Robson - it's available for £34K.
A sticker of Zinedine Zidane, from the Panini Foot 92 album, isn't too far off that amount - and could make you more than £33K.
Erling Haaland is hot property in the footballing world and it's no different in the world of stickers - one from his spell at Red Bull Salzburg is on sale for £8K plus.
While one for another star in the making, Kylian Mbapp , from the Topps UEFA Champions League 2017/18, recently sold for almost £3K.
The study, by 888sport, was carried out to identify 10 of the most valuable and sought after stickers available to buy on auction sites.
A spokesman for 888sport said: "Football stickers are no longer just a hobby, but a way for some people to make serious money.
"You could have a goldmine tucked away just waiting to be discovered."
The debate as to who is better - Messi or Cristiano Ronaldo - rumbles on, but when it comes to soccer adhesives, the Argentine edges it.
A sticker of Messi, from the Panini La Liga 2004/05 collection might bring in £6K or more, while CR7's sticker from the Panini Fotebol 2002/03 album could earn you close to £5K.
Other noteworthy stickers include Pel from the Panini Calciatori 1965/66 collection ( £4,995.00), and David Beckham, from the Panini UEFA Euro 2000 album ( £2,564.00).
While a sticker of recently retired women's football star, Carli Lloyd is currently on sale for more than £2K.
Football stickers were the brainchild of brothers, Giuseppi and Benito Panini who came up with the idea in 1960, eventually founding Panini.
Since then, brands such as Merlin and Topps have arrived on the scene, creating a multimillion-pound industry to a chorus of "got" and "not-got" from children across the globe.
And now, much like retro shirts and programmes, stickers are expensive commodities which are bought and sold - almost like stocks and shares.
A spokesman for 888sport added: "Whether you're a completionist or a sporting memorabilia expert, the internet has changed the world of football stickers in recent years, serving as a one-stop swap shop for the humble football sticker.
"Fans in search of that elusive shiny, or nightmare-inducing haircut on an 80s player portrait shot, can finally fill their boots and complete that dog-eared sticker album from years gone by.
"Not only that, but truly rare stickers are changing hands for eye-watering prices as the fabled "rookie sticker" has seen its value skyrocket in parallel with players' careers."
