Every European (and I guess non-Europeans as well) can vote what our next Euro design will be: https://surveys.ecb.europa.eu/10b/neweuro/
About ten different designs are available and about half of them feature birds instead of boring people.
I really like the bird designs as they symbolise freedom without borders. Hope one of them gets chosen in the end.
Yeah, they’re all good! For me, I is my favorite. J is a close second. I like that the birds all inhabit approximately the same location on J though, all entering that circle. It’s a nice touch. D I feel is too plain, but it may be slightly better functionally. It definitely looks more like currency. I is the most artistic and interesting I think.
