We’ll have to get rid of John Ashcroft first. Otherwise, he’d confiscate any boob-laden money as indecent and lock up everybody at the Treasury 
The oldest coins I have are Swedish öre from just before and just after the turn of the 18th century. I got them from my great-aunt after she died, but nobody has any idea where they came from. My guess is they came from her husband’s side of the family. Most of them are pretty well worn, but it’s damn cool nonetheless. The same “sock” has a bunch of English, French, and German coins from the 19th and 20th centuries as well.
That same great-uncle gave me a whole envelope full of those hyperinflated German banknotes from the early 1920s. Some of them have new values stamped in ink over theface value, but the highest denomination of them all - a 200-billion mark note - is at face value and in good condition. Wouldn’t sell any of those for the world.
I bought a worn coin from a shephard in Carthage that has a ship on one side and two X’s on the other. Some day I’ll get it appraised.
