To wit: the Mint will also sell you in line with Chinese numerology collectible bills with “777”s or “888”s in their SNs with a decorative envelope. Bless the marketing exec who’s finding nontraditional markets for collectible currency.

For Chinese numerology, you'd want 666.

Sevens are a massive number in Chinese numerology: The 7 parts (yin/yang/metals), the 7 steps, 7 captures, etc.

Eights are symbols of prosperity, wealth, generosity, good fortune in business, etc.

Six is a kinda useless number for money -- Smoothness and whatnot are less for money and more for one's tongue. You'd name a wine after a six (I've seen "Dice Wine" referring to 6-sided dice) but not look for it in bills

Well, https://hsbc.banklocationmaps.com/en/chn/shanghai only lists one branch at a street address of 666, and that one is really just sharing the address of the commercial center where it's located, but that still seems like enough for this point.

8 is heavily represented. 6 is a runner-up. 7 doesn't appear to be significant in this context.

Consider the branch phone numbers:

3888 3888

3888 8468

3888 8900

3888 1200

6279 8582

3888 3111

3888 1318

3888 1188

3888 6455

3888 8618

3888 8688

3888 1218

3888 6388

There is technically one 7 in there, but it seems clear that the bank would have preferred not to have it. Counting only the second halves, 8 is overwhelmingly popular, so is 1 (for reasons I don't know), 6 is only barely ahead of what's typical, but still in third place, and 7 doesn't even exist.

For those who are interested: the Chinese character for 8 is a pair of downward lines, close together at the top, far apart at the bottom. Looks a bit like / \. The idea behind it, as far as I know, is that it represents things growing larger, which is why it is of interest where wealth is concerned.

You can just display the character, 八.
