A little off-topic, maybe, but... Back in the ‘90s and a little into the present century, I was working free-lance for a company in Denmark and going over to Europe just about every year. Before the Euro, I’d have to change my Amerikanski dollars into several different currencies as I went from country to country. Usually, by the end of the trip, I’d have some of each currency left over, but it wasn’t enough to be worth changing back to $$, so I just kept it for my next trip. Then came my last trip before the various countries were to change to the Euro. On my next trip, any left-over German marks, Dutch guilders, and French francs would be difficult or impossible to spend, so I spent them while I still could to get rid of them.
Then I realized — “My gosh! I’m spending money like it’s going out of style!”
It is better to save it, if not for yourself, then for your grandkids.
Imagine if you had some Papiermarks, Rentenmarks, or Goldmarks.
Just a quick check of an online seller has Reichsmarks at about 5 times their face value.
