His goalkeeping performance for St Johnstone in a game in which he had to deal with a second-half pummelling from a wasteful Aberdeen side, was, he reckoned, as good as it gets.
Press-ganged into serious action at the age of 41 because of a shoulder injury to regular Saints keeper Alan Mannus, Banks is grateful that he still possesses the zest to compete in the Scottish Premiership and clearly warmed to the task at Pittodrie with a series of excellent stops, especially having been on the receiving end of a four-goal blitz against Dundee United seven days earlier.
"It was a good day," he said. "The lads came out with a clean sheet which was what we wanted after the result at Tannadice. We were hard to beat and we let the attack-minded boys go and do their stuff.
"I am still enjoying my football. If I didn't I wouldn't be doing it anymore because it's not easy at my age; training and working every day, you get a few aches and pains, but I enjoy being around the lads, training every day and making the younger boys better.
"This spell has given me a bit more of an appetite than I've had before when I was playing games here and there. Now, to have got three games on the trot is incredible. It's been five or six years since that happened, when I was at Hearts."
Banks certainly rescued his team on several occasions in a second half dominated by Aberdeen, though the visitors were lively enough on the counter to worry the Pittodrie crowd.
Nigel Hasselbaink taunted and teased the Aberdeen defence frequently in the opening 45 minutes and he presented David Wotherspoon with a chance that prompted a spectacular save from Jamie Langfield,
Aberdeen manager Derek McInnes knew changes were required at the break, particularly to negate the influence of Chris Millar, Gary McDonald and Murray Davidson in the St Johnstone midfield.
By then, Banks had kept out a volley from Gregg Wylde but, with the second half only moments old, he knew little of Niall McGinn's strike, other than it had hit his crossbar before Josh Magennis fumbled the ball past.
Then there was Peter Pawlett's sizzler from distance, beaten away by the Saints keeper, followed by a similar piece of action, this time preventing Cammy Smith's long-range shot from opening the scoring.
Towards the end, however, Davidson's miss from six yards brought gasps from the crowd and left Tommy Wright, the St Johnstone manager, ruing what might have been.
McInnes may have been satisfied that his side had not conceded a goal, but there is a feeling that his striking department is failing in its duty.
Aberdeen have now played four consecutive games where, worryingly for their fans, they have failed to score at all in open play.
"I was disappointed we never played with any real tempo in the first half," McInnes said, "and I thought we needed to show ourselves more and force the issue more. I thought we were very tepid, to say the least, in the first 45 minutes.
"As the home team the emphasis was on us to go and try and force the issue. We had more control of the game in the second half and St Johnstone have their keeper to thank for some terrific saves and credit to him for that. He was outstanding."
