Could you help me explain this sentence?

“Taking the coins to the bank was always a big production.”
What does “a big production” mean here?
I posted this question several days ago, but I find it disappear in this forum.So I post it again. Thank you very much fou your answer!

The following is the context:
The pickle jar as far back as I can remember sat on the floor beside the dresser in my parents' bedroom. When he got ready for bed, Dad would empty his pockets and toss his coins into the jar.
As a small boy I was always fascinated at the sounds the coins made as they were dropped into the jar. They ended with a merry jingle when the jar was almost empty. Then the tones gradually muted to a dull thud as the jar was filled. I used to squat on the floor in front of the jar and admire the copper and silver circles that glinted like a pirate's treasure when the sun poured through the bedroom window.
When the jar was filled, Dad would sit at the kitchen table and roll the coins before taking them to the bank. Taking the coins to the bank was always a big production. Stacked neatly in a small cardboard box, the coins were placed between Dad and me on the seat of his old truck..
