Just got an ad for their upcoming auction via a CDN sponsored spam email. I know it's not a huge deal, but clicking the above picture in the email takes me to https://www.invaluable.com/. (I prefer it when the name of the company actually matches the website, but there's obviously no rule that says that has to be the case...)
There was another one of these auction sites that claimed it was confiscated police stuff. It was very shady. Maybe this is different, but I say grain of salt until otherwise discovered to be honest. The other one sold stuff, but photos were jacked, prices were jacked, shipping was jacked, complaints were jacked, etc. Tread lightly.
Go read their about page and then find their commercial side page which will explain who they were. Last one of those I chased down, the only police involved was ticketing illegally parked buyers at the auction.
