Game won is worth much more than it is?

its a common bug in the price tag of steam

This might be bundled in steam ,so a price glitch , will come back to normal price with time :)

Daedalic bug. Will go away once the sale of this package ends, and come back when it is on a 90% sale again.

Chains of Satinav is also often priced up for a while, afterwards it goes down again.
This is usually done when the game is on sale. So instead of 20$ with 50% discount, they have 100$ with 90% discount. Both resulting in 10$. But the 90$ discount looks more interesting.
(Numbers pulled out of thin air)

Blacklisted for bad ratio!
Just kidding. Obviously.

Its happening! Inflating pricings before sale!! See their evil undressed before your eyes, the whole steam sale is a scam, a scam!! The end of days is upon us, the devil himself posing as god Gaben is coming for our wallets blood in his eyes with false promises and prices!!! We always said it was coming, heres the proof- the end is upon us!!!

...or its a bug.

and if you're in another country sometimes it'll change to their currency too!
