Where is the Coin in the Transaction Hash Chain?
Where is the coin in the diagram above


Nowhere really.

The "Transaction" part contains information about the movement of coins (or rather of fractional values). It doesn't really contain a coin.

To work out where the coins are (notionally), you read all the transactions in all the blocks since the first one and see at which addresses everything ended up.

It's like the paper pages of an accounting-book that keeps track of the movement of conch shells, except there are no actual conch shells. Certainly you won't find any conch shells in the accounting book. Bitcoins are imaginary conch shells - they don't actually exist anywhere¹.



No actual gold coins to be found in between the pages of this ledger

Also true of USD really. Greenbacks are just pieces of paper that are part of a distributed accounting system.
