If you don't wish to see all of the rewards as they populate, but just want to see the gold values. They are listed below.

I decided against compiling all of the item data itself due to lack of time and the fact that 600+ crates is actually still pretty small for "large number theory" when the variables are so vast on a drop system like Jubilee crates. You could theoretically open this exact number of crates and never get a drop over 100,000g, or you could open half of them and get 1 item worth as much as all of my drops give or take.
BUT the average based on my outcomes would have you expecting around 496,889g
And based on my own human perception of the rewards in the current market on PC-NA. I would wager you should expect no less than 250,000g-350,000g per 70 crates. And typically, well beyond those numbers.
Character 1: 79 boxes – 643,000 gold (3:53 - 4:01)
Character 2: 70 boxes – 400,000 gold (6:17 - 6:27)
Character 3: 70 boxes – 385,000 gold (9:35 - 9:47)
Character 4: 70 boxes – 450,000 gold (11:55 - 12:00)
Character 5: 70 boxes – 802,000 gold (13:59 - 14:00)
Character 6: 70 boxes – 547,000 gold (16:09 - 16:15)
Character 7: 70 boxes – 331,000 gold (18:19 - 18:22)
Character 8: 69 boxes – 564,000 gold (20:19 - 20:24)
Character 9: 69 boxes – 357,000 gold (22:40 - 22:45)
Grand Total: 637 boxes for an estimated 4,472,000 gold in item value (23:08 - 23:15).
