Picked up a 2019 50p Paddinton Bear (St Pauls) piece while shopping the other day. While having a look I can see that the uncirculated ones go for a fair amount, and you can get silver ones as well. I'm not sure if I've got anything exciting or if it's just worth the 50p?
I would say normal (business) strike. They are not particularly scarce although there are collectors for them - mostly kids or doting grandmothers! If someone needs on, they might give you £1 or £2, but unlikely more.
