Looking For Information - 1920-S Austrian Stamps

Hi forumites, I'm not actually a collector, so I don't know all that much about stamps. I picked up this old postcard at an antique store and was hoping to find some info about it. The card is dated 29.12.24, so I'm assuming its from 1924, but it could be 1929 as well. There are two 100 krone stamps, and one 500.

I guess what I want to know is:
How common were these stamps?
How much would it have cost to send in today's currency?
How far would the 700kr have sent this card? (I found it in BC, Canada)
Really any other info would be appreciated, I tried looking around but I couldn't find much. Thanks!

For some reason I'm getting a 404 error when I try to upload the images, so here's a link to where I have them in a google drive:

(Apologies for poor quality, my phone's camera isn't the best)

Edit - I'm an idiot and thought the stamps were from Norway for some reason. My bad.

These are Austrian stamps

The stamps are Austrian, not Norwegian. The top of each stamp says "Österreich," not "Norge." What about them or the postcard led you to think Norway?

That aside, these stamps are incredibly common. About 174m of the 100kr were printed, and 161m of the 500kr.

Wow, that was dumb of me. I couldn't really read the text at the top and I saw 'Krone' so I guess I just assumed. Thank you!

These are very common stamps. Any value is in the postcard as a whole. We'd appreciate it if we could see at least the whole address side.

Austria had just come out of a hyperinflationary period in early 1923, accounting for the high face values. Postage would have been the equivalent of a couple US cents.

How far? What is the destination of the card? There's your answer. Unless perhaps sent by a collector to another collector, people normally didn't overpay postage.
