Gray Coin

Gray Coins are coins that appear in Super Mario World. Pressing a gray P-Switch turns all enemies into Gray Coins for a limited time. However, Gray Coins work differently from standard coins in this game; if enough are collected, they give extra lives, similar to jumping on numerous enemies in succession. In certain levels, a trick involving hordes of enemies and a gray P-Switch can be executed to earn dozens of extra lives. This goes in order with collecting Gray Coins:


 * 400 - 1 Silver Coin
 * 800 - 2 Silver Coins
 * 1000 - 3 Silver Coins
 * 2000 - 4 Silver Coins
 * 4000 - 5 Silver Coins
 * 8000 - 6 Silver Coins
 * 1UP - 7 Silver Coins
 * 2UP - 8 Silver Coins
 * 3UP - 9 Silver Coins or more
