Frank WakefieldV100 Willards Chocolate and an E101 anonymous are correct.
The V100 should have large borders around what you have there. Quite a bit of the card has been trimmed away.
The E101 looks authentic, although the wear on the edges looks slightly odd. I'd shine a black light on it to see if it fluoresces. A genuine E101 won't, a reprint will glow. $400 seems optimistic, $250 to $300 seems reasonable. Maybe less the way stuff's selling at present. I think it's a good looking card. Slab folks would be up in arms about the writing on the back.
