Are these lil fellas worth anything to anyone?

I recently started playing again after barely touching the game since 2019, I was scrolling through the sub and saw a few asking about these costumed Pikachus & some strange love for stonjourner? As I say, recently started playing again (Mostly to get pokemon for champions, so if people want to trade things I’m not overly fussed about stats) – I also saw that any pokemon in your storage from 2016-19 that gets traded guarantees a lucky trade? I have an abundance and want sure the best way to make use? Thanks 🙂
