The Drive for Five remains on track for the Boys in Blue - despite a nail-biting clash for the ages with great rivals Kerry.
A Dean Rock free which veered wide in the final seconds ensured the sides finished deadlocked on 1-16 apiece in Croke Park.
With no All-Ireland champion decided yet, it was the GAA and Dublin city who were the big winners - as up to €14m is estimated to reach the coffers of Croker and the capital's hotels and bars.
Graeme McQueen of Dublin's Chamber of Commerce said a big windfall is to be expected when the Dubs take on the Kingdom on Saturday, September 14.
"Between ticket sales and match programmes etc, the GAA indicate a gross spend of around €6.5m for an All-Ireland Final," Mr McQueen said.
"Then you have the spend on food, beverages, travelling and accommodation, which is estimated to be around €7m.
"A replay is good news for the hotels and pubs in Dublin and also around the country as people head out to watch the match.
"Events are huge now in terms of getting people to go out, so we'd expect another busy weekend in the city, and hopefully a Dublin win, of course," he added.
Among those in attendance was avid Dubs fan Sean Cox, who was pictured cheering the team on.
Mr Cox is still recovering following a horror assault in Liverpool last year as he was making his way to a match.
The clamour for tickets begins already for avid supporters of the Boys in Blue.
An extra estimated 10,000 tickets are expected to become available for Dublin and Kerry fans.
This is the estimated allocation provided to the competing counties of the All-Ireland Minor Football Final between Cork and Galway which took place before yesterday's senior match.
The GAA will also reduce the price of tickets for the replay, with full details expected to be released today.
A reduction of at least €20 is anticipated on the €90 stand ticket. The last time an All-Ireland Final went to a replay, the Dublin-Mayo match in 2016, the cost of stand tickets dropped from €80 to €60.
Terrace tickets were also reduced from €40 to €30.
The Drive for Five All-Ireland titles in a row will ensure a ticketing frenzy as Dublin get a second bite of the cherry.
Former Hill 16 hero Ciaran Whelan felt Dublin underperformed and will have to improve for the replay. "I don't think Dublin played to the level they can and there's a lot of scope for improvement," he said.
"Kerry caught Dublin by surprise in some facets and they got out of jail.
"At one point, I though it was gone, there were a few things that were unlike Dublin to do."
