But collectors don’t care about age—they care about rarity.
And when it comes to currency, “fancy serial numbers” are like winning the lottery.
These are patterns so unique, so symmetrical, or so repetitive that they’re considered “eye appeal” collectibles — and collectors will pay big for them.
Even better?
They’re still legal tender.
So you can either spend them…
Or sell them for way more than face value.
