These 80 custom metal coins are designed specifically for Expeditions and Scythe by artist Jakub Rozalski. They include denominations of $1, $3, $5, $10, and $20.
The only difference between this pack and the original Scythe metal coin pack is that the $5 coins now have a distinctly red hue to better differentiate them from the $10 coins. You can buy just the new $5 coins (x15) here.
