Currency

In Exandria, the most common form of currency are coins, or "pieces", made from various metals of different values. The metals and denominations of coins minted by Exandria's Post-Divergence nations appear to be fairly standardized. The three most common coins from lowest to highest in value are the copper piece (cp), silver piece (sp), and gold piece (gp). Two additional denominations, the electrum piece (ep) and platinum piece (pp), were common during the Age of Arcanum. While platinum pieces appear to still be minted Post-Divergence, they are only used for high-value transactions, and electrum coins are exceedingly rare.

The use of currency minted in one nation is generally still accepted in another, as they hold the same value, as are ancient coins scavenged from Pre-Divergence ruins. While nations seem to give the coins they mint unique names (for example, a Concordian gold piece is called a "galley"), coins are generally called by the metal from which they are made.

Around 823 PD, about twenty years before Campaign 3, the Variant Coinstores of Duman in Jrusar, Marquet, changed the emblem pressed into their coins and withdrew them from circulation. This gave these coins additional value as they commemorate a moment in time.

Denominations and exchange rate
Generally speaking, one denomination of coinage is worth ten of the lower denomination. Thus, ten copper pieces are worth one silver piece, ten silver pieces are worth one gold piece, and ten gold pieces are worth one platinum piece.

The rarely used electrum piece is the exception, being worth five silver pieces. Two electrum pieces are worth one gold piece.

Trivia

 * From the surface of Exandria, the sun's disk is said to be the size of a gold piece, though the size of said piece is never specified.
 * In a now deleted tweet, Deven Rue posted designs for Dwendalian coinage that she created as gifts to commemorate the release of Explorer's Guide to Wildemount. The coins were pentagonal in shape and had names for each denomination. The post was deleted over concerns of fans making reproductions of her designs against her permission.
