20 Coins are coins that appear in Mario & Luigi: Partners in Time. As their name implies, each of these blue coins are worth twenty normal Coins. They are uncommon and are mostly found in ? Blocks (usually hard-to-reach ones), and sometimes found in the very long chasms in Thwomp Caverns, along with gold coins.
