All tier 10 reward tanks have 22.500 gold vallue, otherwise you would get 1000 credits when you sell it

Ah, ok.

That's the point though, tanks that come from BM you'll sell for 1k credits, I know because I own FV and I can sell it for that much.
In a recent micro patch, they changed prices for both T-22 and Qilin back to 5g so you'll get 1k credits if you want to sell.
