My thoughts exactly! every time I see one, I think that! Or that it got wet and someone tried to iron it dry and ended up scorching it…
The thing I don’t like about them is that when I’m counting the drawer at work I feel compelled to sort out the tens by color now. And I hate things that trigger my latent OCD.
Eh, not exactly. Both gold & silver dollars go way back. And then there was the “Eagle” which was a sizable gold ten-dollar coin, back when ten dollars was a lot of scratch. Also half eagles & double eagles.
I think that the Swiss have come up with the best solution to this - their notes are all the same width, but each denomination is slightly longer than the last. This makes them stack very neatly, especially when arranged in order of denomination, while still being easily distinguishable by size (and indeed shape - they’re the only notes I’ve seen where denominations differ by shape as well as size and colour). It doesn’t hurt that Swiss notes are attractively designed.
