The guy is swearing these are all legit, and that Crumb was released a few years ago on card?
He's either clueless, or a scammer.
Crumb has NEVER been issued on a card of any kind, except as an accessory to the POTJ deluxe Amanaman figure, and that sculpt is very different to the vintage one.
The loose EV-9D9 is POTF2 from 1996/7.
The blue astromech is R2-B1, from the Episode I line, missing all of its accessories.
If the guy is scamming, then you need to verify the carded vintage are not recards/repros, that Lumat's bow isn't repro, and that none of the others (including the mint looking Blue Snaggletooth) have not been repainted.
