Alright, so I wanted to figure out what the most expensive League of Legends skin was. I started by firing up the game, and then I went straight to the store. I browsed through all the tabs, checking out each skin category one by one. I noticed that the Ultimate skins were pretty pricey, usually sitting around 3250 RP, but I was sure there was something even more expensive out there.
Then I remembered that some skins are not always available in the store, they’re called Legacy skins. So I started digging around the internet, doing some searches. I found some forum posts and articles talking about rare and expensive skins. It got a bit overwhelming ’cause there are a lot of them, and getting a concrete price was tough. Prices fluctuate depending on where you look – whether it’s from Riot’s official store when they rarely make them available, or some third-party sites selling accounts with these skins.

After looking around for a while, I stumbled upon discussions about the rarest skins like PAX Twisted Fate, Silver Kayle, and Black Alistar. These were given out way back when at special events or as part of collector’s editions. They’re super rare, and some players estimate their value to be in the hundreds or even thousands of dollars if you were to buy an account that has them.
However, I was more interested in skins that I could theoretically purchase right now, even if it involved some waiting. After some more digging, I found that the Prestige skins, especially the older ones that are no longer obtainable through events, can be pretty expensive. You have to get them through the Mythic Essence shop, and it takes a lot of grinding or a lot of money to get enough Mythic Essence.
I went back into the game and checked out the Mythic Essence shop. These Prestige skins rotate, and you need a whole bunch of Mythic Essence to unlock them. This could take months of playing and completing missions, or you’d have to buy a ton of loot boxes to get enough essence.
So, after all this digging and checking, I found that the most expensive League skins are those rare, limited ones like PAX Twisted Fate. But in terms of what you can get your hands on in a practical sense, those Prestige skins from the Mythic Essence shop are the priciest, because you can technically still get them, it just costs a ton in either time or money to get that Mythic Essence.
