Located at 48 Wall Street is the Museum of American Finance. I was happy to see it (entry I think was $10) but no mindblowing banknotes on display from memory. It was educational and one exhibit shows the national debt increasing rapidly in real time..... every single second!
plus, if you have actually never set foot on Wall Street - you should!
The statue of George Washington is where Cisco's sub-treasury was. To be a major bank you needed to be close enough to that spot to wheel a cart full of gold to your own vault. The presence of the stock exchange was only a secondary consideration.
