A serialized MTG Ragavan card from March of the Machine is selling for an outrageous amount

Serialized double-rainbow Magic: The Gathering cards have returned to Standard-legal set releases through March of the Machine with a serialized Ragavan, Nimble Piliferer potentially being offered for over $6,000 before the set even releases. 

Scheduled to become available on April 14 through the start of prerelease events, the March of the Machine (MOM) set contains serialized Multiverse Legends and Praetors that are expected to sell for thousands on the secondary market. The highest-priced non-serialized MOM card so far is the Halo foil Ragavan, Nimble Pilferer. And the pirate monkey became the highest-selling serialized card today through Ben Bleiweiss cracking an 001/500 serialized version of Ragavan.
