How is card value calculated?

I have a common card in my deck valued at 0.45, more than rares. It was not an asking/bid price either. I had previously assumed cards were valued based on their rarity, but it doesn’t seem to be the case?

Junk value is based on rarity. Estimated market value is based on the match price of previous trades.

sometimes it ignores certain trades though, I don't know if it's an anti puppet thing but if it is it doesn't always work
