Trivia

• Alpha Coin is a returning Item from The Devil's Harvest MOD for The Binding of Isaac: Afterbirth+.
• Alpha Coin was unused in the initial The Binding of Isaac: Afterbirth+ release of Fiend Folio.
• Alpha Coin's interaction when used in the Mega Satan arena is an obscure reference to a meme mod titled gordens dad maeg a sata (sic), which itself is based on a video edit made by @ictonent of Russell from the game Half Life: Alyx repeatedly saying the phrase "I'm with you".
