How TF would we know?
Other people in this forum might have greater knowledge than you or me. If you aren’t one of those people, then this question isn’t directed towards you.
I had a game like, or similar to, this (at least one). I would instinctively expect closer to 3000. I had multiple battle hero awards and got no 500 silver adders for them.
I assume there’s something they need to work out since the update.
No players have that knowledge - how silver is awarded is a mystery black box. But I do notice you do not have Premium?
The lack of battle hero awards silver is reported multiple times today on the bug reporting page… not clear to me if that applies here.
Thank you for providing this information; it explains a lot now.
Just example, I dont know the silver calculation.
For 3000 silver you need something like this:
(fun fact: there is another bug, you dont even get the silver mentioned on the scoreboard, but less 
)
Why is the silver earning rate so low? I could’ve sworn it was higher.
There is some visual problems with receiving silver
5 silver = 47xp
9365*5/47=996.27
as to why you have extra 3.73 silver, it is probably some rounding issue…
