What was the name of the service that published Bitcoin’s first exchange rate in October 2009?

New Liberty Standard published Bitcoin’s first exchange rate in October 2009.

The service was created by user “NewLibertyStandard” on the Bitcointalk forum. Its early pricing method estimated Bitcoin’s value from the electricity needed to generate it, rather than from an established market order book.

On 5 October 2009, New Liberty Standard listed an exchange rate of 1,309.03 bitcoin per U.S. dollar. This valuation helped turn Bitcoin from a purely experimental payment system into something that could be discussed in monetary terms.

The rate was not the same as a modern exchange price. Bitcoin trading was still extremely limited, and the first widely remembered commercial purchase came later, in May 2010, when Laszlo Hanyecz paid 10,000 bitcoin for two pizzas. Mt. Gox, launched in 2010, became a much larger exchange afterward.
