I am not sure if this counts, but anyhow...
Several years ago we sold our high-rise apartment here in Tokyo (where real estate prices are high, you might have heard) to move to a single-family house. I don't know how it works in the States, but when we had the sale all arranged, the bankers scheduled the meetup for the sale at one of their offices.
The buyers showed up, with their bank officers, and we showed up with ours. When we all signed on the dotted lines (actually here we use registered family seals instead of signatures), the buyers' banker pulled out a brick of 10,000yen notes (equivalent to $100 bills) for the full purchase price and handed it to them. They presented it to us, buying the apartment. I accepted it, then presented it to my banker to apply to our home loans (old and new).
Both the buyer and I had a certain giddy gleam in our eyes as we pushed this huge stack of yen about. "Oh here, old pal, let me give this stack of half a million dollars in cash!" "Quite right, old boy, I'll just take that off your hands!"
The bankers, who have probably gone through this exchange hundreds of times, looked on disinterestedly.
