The National League has produced some household names in English football, and it is a division that often offers incredible value for money.
While clubs in the fifth tier may not have the financial might that those in the Premier League and the EFL possess, on occasion, they have paid out significant fees to secure talent.
Of course, the majority of hefty transfers have involved players vacating the National League with the dream of following in Jamie Vardy's footsteps.
Here, DAZN News looks back at the highest estimated transfer fees of incoming and outgoing players in National League history.

When Max Kilman left Maidenhead United to join Premier League side Wolves for an initial £40,000, the Stones could not have imagined the future windfall they would receive.
The Old Gold took a punt on the central defender in 2018, and he became a first-team regular for years to come before securing a £40million move to West Ham United in 2024.
As is commonplace in the National League now, clubs ensure a sell-on clause is inserted into transfer deals so they can yield a substantial future fee.
In the case of Kilman, Maidenhead were entitled to a reported 10% of any future deal, meaning that they bagged a total of £4.4million - a significant amount of money for any Non-League club.
"This money that's coming to us will help secure Maidenhead United's first team, women's team, all the community things we do and our infrastructure plans," club chairman Peter Griffin told the Maidenhead Advertiser in 2024.
Peterborough United have a history of targeting the National League for affordable prospects with high ceilings, with their most expensive outlay on Woking goalkeeper Shwan Jalal.
Like most of the transfers at the Non-League level, the fee for this deal was undisclosed, but it is estimated that Posh paid £510,000 to sign the shot-stopper in 2007.
The Baghdad-born keeper started his career with Tottenham and then had spells with Sheffield Wednesday and Leeds United before joining the Cards.
Jalal barely featured for Peterborough and made most of his appearances for Bournemouth while they were in League One.
Now, the former player is working as a goalkeeping coach for Premier League side Newcastle United.

You will have to get used to seeing Peterborough in this article because they feature prominantly.
When Posh signed Jack Taylor from Barnet in 2020, the midfielder already had EFL pedigree, having made 52 appearances in League Two before the Bees were relegated to the National League.
Unlike the deal to bring Jalal to the Weston Homes Stadium, this one was a roaring success as Taylor went on to make 137 appearances for the club while guiding them to the Championship in 2021.
Posh made a profit on the central midfielder when they sold him to Ipswich Town for an undisclosed fee in 2023, and he was a regular during their season in the Premier League.

Shock horror, it is the return of Posh, who this time raided National League side Rochdale in the summer of 2024 for upcoming talent George Nevett.
The teenage centre-back made 34 appearances in the fifth tier before Peterborough snapped him up for an estimated £400,000.
"When I look at young players like Ronnie Edwards, who came here from Barnet at a similar age to me, I really do have role models for what I am looking to achieve in my own career," Nevett told the Peterborough website.
Posh boss Darren Ferguson stated that the club had been watching the defender closely in the National League, and it would be unsurprising if they are not scouting the division in detail this term.

Josh Stones is an anomaly on the list as he moved from the EFL to the National League.
Although the forward struggled to make an impact at League One outfit Wigan Athletic, he has been turning heads in the National League since signing for York City for an estimated £360,000.
While Stones was unable to help the Minstermen achieve promotion at the end of the 2024-25 season, he has chipped in with some valuable goals and assists for the title challengers since.
York's drive to return to the Football League is evident, given that they also paid a substantial figure for Dipo Akinyemi in 2023, but will their spending pay off?
