I went to the Corrado Romano sale at Stacks in '89 and they did the viewing in NYC. Back then they had multiple stations manned by a group of people that handled the viewing. They would bring out a box of the lot range you wanted to look at and let you go through them one by one while they watched you. There was no fanfare around any particular coin. The old man's 1792 silver centered cent was in a box with the other coins in that lot range and if you didn't know what it was, you would never know. Now I guess everything is in a slab which makes it easier and the boxes are PCGS and NGC boxes. I'm sure the 1804 dollar is just another coin in the box. I flew out to NYC for that sale. You didn't used to be able to look at Hi Res images on a computer and bid online, but you had paper catalogs that you wrote in to guide you during the auction as you got to see the lot only while viewing, not while the auction was happening like online participants do now. You had to wait for your coin to show up and not let your attention waiver or you might miss your lot. And you had paddles with your number on it. I haven't held an auction paddle in 20 years.
