In order to make money more portable the monetary system has been chanced as follows:
10 copper = 1 silver
20 silver = 1 gold
2 electrum = 1 gold
5 gold = 1 platinum
1 bar of any metal equals 100 coins of the same.
All prices in the PHB UA and DMG for gold are now silver. All goods that are silver and copper are 1/10 of the value listed, in the silver.
