FWIW: when I opened mine in Feb 2016 (my first Discover card) the starting CL was $12,500, My wife got about the same a year later.
This was on the low side of my other cards
I don't know that Discover is really known for generous limits, especially considering your other limits. I certainly would not expect a huge approval. That said, Discover is (for some) flexible with CLI over time.
Welcome, @Anonymous.
One thing about Discover is their unpredictability. myFICO Member A can report one experience with Member B reporting exactly the opposite.
But we know they like files like yours. I woudn't necessarily expect a huge limit right away. Getting your largest limit thus far wouldn't surprise me, though. And I'd be surprised if you weren't well positioned for credit limit increases.
Welcome to MyFico!
My first (Discover It) card started at $5500, now $21,500
My second (Discover It Miles) card was $1,000, now $7,000
So, even with lower limits, Discover cards can grow.
