Hal Finney must have accumulated a ton of bitcoin.
What ever happened to them?
After his death, have they been sold?
They sold a lot of it to pay for his medical treatment in the years before his death, plus teh costs of cryonicly freezing him:
Considering that the price range for cryonics range from $28000-$200k depending on whether you only want your brain or whole body to be frozen, it's possible that they really sold those bitcoins when Hal was still alive. ALS is no joke expensive to treat--or lessen the effects and help the affected individual comfortable since there really is no medically-proven method that cures it--and it might be that the Finney estate exhausted their money over time.
He died in 2014, so they sold back then (way before bitcoin started to surge in price). They got about $12,000 for the lot.
If Hal was mining ever since the start of the network, this will put him to the hundred thousands of bitcoin on the safe, if not million/s IMO, so I don't think $12000 is the right valuation for what he has in store for his heir. What the $12000 stands for, perhaps, is the donation they received when Hal was still alive.
