Since EA FC 25 Ultimate Team follows a "fantasy" approach to football, you'll see Special Cards that outperform their Gold (or Silver) counterparts. Sometimes, the developers add more stats, traits, or new positions. For example, the Harry Kane Gold Card (90) has lower attributes than the TOTW (Team of the Week) Special Card (92).

FC 25 coins serve as a virtual currency within the game. Players can use FC 25 coins to buy in-game items such as player packs, consumables, and other virtual. so you can buy FC FUT Coins at mmoexp.com
