That's just one surface, you should see the drawers. I wouldn't want to hear what my wife would say if she had any clue what they all cost.
I'm in the majority here, which doesn't seem to happen often, since I also use Excel. I also track the bullion values of both numismatic and non-numismatic items in the same spreadsheet by AGW and ASW and update the values every so often. This practice sprinkles an illusion of organization over utter chaos. But it seems to work. I think.
