Clocked it earlier.
“If it looks too good to be true, it probably is” is the age old saying.
As mentioned above a scam, you’d think they would at least try to match the going rate. Still some wouldn’t know and will attempt to purchase no doubt at some point. Seen it before with other ‘cheap’ cards.
Similiar thing with the proxies aka fakes going on where the naive will still attempt to buy thinking they’ve got a steal.
A few years ago while browsing new on ebay I bought a sealed pokemon emerald for $75. Then the same thing popped up on new a few hours later and I knew I just put $75 in limbo until I could file a case and get my money back. No one is selling that card for 1k.
