My blockchain might be a little rusty, but is it possible to tell the order in which a coin was mined (vs the total) from the information in the chain?

If so, should be possible to find satoshi coins relatively easily, no?

Bitcoin doesn’t really work like that, a “coin” is just a value tied to an address, so individual coins are never transferred. What you can do is see all the incoming transactions to an address to identify which addresses received the earliest mined coins.

Good point. Is there a way to see when an address was created?

To date the opening of the account?

It isn’t proof but it’s definitely evidence.
