# 4. Currencies

## Premium Currency

<mark style="color:orange;">**Nuggies**</mark> are the premium non-tradeable in-game currency and can be used to make all [Auction House](/game-guide/how-to-play/7.-auction-house.md) purchases, pay all crafting fees and place Bounties. Nuggies are purchasable from the cash shop.

## Progression Currency

<mark style="color:orange;">**Doubloons**</mark> are a non-tradeable reward currency collected by completing key objectives in Pillage Wars (like capturing towers), and are used for other purposes, such as crafting, rankings, or earning Event Currencies.

## Event Currencies

Event currencies are associated with limited-time events, like airdrops or seasonal holidays. These are only in-game for a short period of time. You can qualify to earn Event Currencies by having the corresponding Event Pass or [Pirate Pass](/game-guide/how-to-play/11.-pirate-pass.md). If you have the appropriate event pass or a Pirate Pass, then each time you earn a Doubloon in-game ("Piracy") you'll also earn event currencies. You can also earn additional Event Currencies via quests.

You can stack Event Passes and Pirate Passes to increase your Event Multiplier, with each pass adding +1x to your respective Event Multiplier for that event.&#x20;

Current event currencies are:

* <mark style="color:orange;">**mXP**</mark>, part of the Abstract chain launch promotion, which converts to Abstract XP at some undisclosed rate, which ostensibly may convert to an $ABS airdrop on a future date, which has neither been determined nor promised.
