I don't think since the US government has decided the adoption of bitcoin for it Fed reserve and being the highest nation holding bitcoin, they would likely keep the recovered bitcoins that is worth $6.5 billion from the Silk and add up to their initial holding.
The vision of the US government as Donald Trump emerges office is to accumulate infinite number of bitcoins which these seized recovered funds maybe channeled over to the Fed reserve account of their bitcoins.
Knowing the friendly differences between Biden and Trump over bitcoin, we all we'd know how strong hold and supportive Trump had been over it speculative adoption to provide more to its values, I'd doubt if the DOJ attorney general would forward to sell them off because he'd be questioned to account what the funds was used for knowing the attorney general was Bidden's appointee to lead the DOJ.
So I think he might end up in jail by Trump if sold the recovered Silk bitcoins instead would be added to the already national reserve.
