Vienna ticket prices

Does anyone know what the face value of different Vienna tickets was/is? I'm mostly interested in GA standing tickets (because I assume those are the cheapest), though any info on what kind of tickets I would be able to get for up to 200€ per ticket would be highly appreciated!

Asking so that I can actually tell if people are scalpers or not when I see a resale offer, before I contact the seller. Thanks! 😊
