Euro Serial Numbers, Please Help Me

As a general rule, if you have to ask whether a serial number is cool, it isn't. There are a couple that might make you think "oh, that's sort of interesting", but there's nothing there that would make me think anything beyond that. It's kind of cool seeing the red 333322 on the first note, but it's not going to give it any sort of premium (the people who can afford to collect 50s are going to want both much cooler numbers (ie solid 3s) and much better condition notes).

Nothing here is worth any premium - of course, that's not to say you can't personally save any you like, but they're never going to be worth more than face value.

MY understanding of the fancy serial number collector market is that pretty much the only thing valued are:

1. Very low serial numbers, possibly under 100 or maybe less
2. Solid numbers
3. radar: serial number reads the same backwards and forwards
4. ladder: numbers rise in sequence, like 12345678, or in reverse.

Plus, with modern notes they really need to be crisp uncirculated.
