Path of Exile 2's Currency Exchange is a vital feature, allowing you to trade lower-tier currencies for higher-tier ones, crucial for player trading and crafting. However, determining the current exchange rates can be tricky due to their constant fluctuation.
Because PoE 2 currency exchange rates are dynamic and market-driven, the only reliable way to check them is in-game.
How to Check Currency Exchange Rates in PoE 2

To access the Currency Exchange, speak to the gambling vendor in any Act after reaching Cruel difficulty. The exchange menu presents two currency selection boxes:
"Want": Select the currency you desire. For example, to find the Divine Orb price, choose Divine Orb from this list.
"Have": Select the currency you're offering in exchange. To see the Divine Orb's price in Exalted Orbs, choose Exalted Orb from your available currencies.
The conversion ratio will appear between the boxes. This shows how many Exalted Orbs are needed to obtain one Divine Orb (or vice-versa if you select Divine Orb in "Have" and Exalted Orb in "Want").
This process works for any currency pair. Remember, rates change frequently, so check often for the best deals. If a conversion isn't available (e.g., Divine Orb for Scrolls of Wisdom), no ratio will be displayed.
