I don't know that it's the RAREST card, I own the ONLY ERROR card that came from the Topps medley of cards for 2018. Your card was made intentionally.... the real UNICORN is the one in a million, mistake card. Most collectors put that ahead of a 1/1 card for "Rarity". Just sayin', also...I have a Cryptocurrency 3-in-1 card that's a 1/1 as well. So, you're not the only one to have one of one's. But, hey, your card is definitely cool. Congrats!! 
Anyone know what the 1/1 Rookie card is worth? The Black Lotus Magic card goes for over $350k This is the rarest of rare rookie cards for bitcoin. It's not a blank back or mini card, it is the 1/1 Standard sized card. This is the rarest card pulled from hundred of thousands of packs
