WTF are you on about? all funds are spendable. all funds are real, no matter what date they were received
that address contains:
1 coinbase and 43 address to address transactions
a coinbase is spendable. but being a coinbase is not a transaction in my eyes. its why it was given the term 'coinbase' to separate it into a different terminology from regular transactions.
but as i said ALL the funds are spendable, all the funds are real.
i know this is digressing off the OP's question. and being pedantic, and that franky1 already knows about it, but the very first coinbase is not spendable due to a quirk in the Bitcoin code. Every coinbase after that is spendable so SmartIphone would consider the second block's coinbase as the first transaction.
However, I take the majority's view that the pizza sale was the first Bitcoin transaction.
