FIFA Ultimate Team because players sold the FUT Hero items
Although EA rectified the error around 25 minutes after FIFA 23 Coins releasing the pack, it wasn't enough to stop millions of coins in value from being removed off FIFA Ultimate Team because players sold the FUT Hero items in a out of panic due to the massive influx of inventory.
FUT Hero items are very scarce players and are available in certain packs in Ultimate Team. FUT Hero cards are offered to players who have been a major contributor to a club or have become a cult favourite for example, like Former Manchester United midfielder Park Ji-Sung.
Due to the item's rare, they're typically very expensive on FIFA 23 Ultimate Team's virtual transfer market with some such as Yaya Toure being sold in the region of 1.9 million coins which a reputable third-party selling website estimates at just below PS400.
In the end, EA mistakenly released this pack to flood the market with a massive amount of these items and saw the costs drop quickly Some players lost up to 100,000 FUT coins in value. This is about PS200 when purchased through a third-party.
EA is yet to issue a statement regarding the error. But the impact on the market is long-lasting. Many, if perhaps all players have lost value and although the market has slightly recovered following the removal from the pack and resultant shortage in FUT Hero items, the loss of coins will not be able to be reversed.
Anyone who was able to buy the pack might have some luck it was advertised as not tradeable (meaning it can't be sold in the market for transfer) In the past, where EA has offered a pack with an incorrect description, they typically compensate customers who bought the original pack. That means some gamers could be FUT 23 buy Coins given up to two FUT Hero cards for as little as 25,000 coins.
