How do I organise my Beanies/baseball caps?

[still standing]

Over the years, I've accumulated quite a number of very nice beanies and baseball caps all with some type of horsy logo, as prizes, helpers' Thank You, sponsors gifts, etc.
They are just piled up among my riding gear at home but I would like to find some way of tidying or hanging them, as I have quite a lot but only use one at a time! Also, some I will never wear (not my colour!) but charity shops don't want them and I will not just throw away good items. The beanies aren't so difficult as I lay them on top of each other but the baseball caps are all getting crushed and have folds in them.
So... any suggestions please, both for tidying some and disposing of others?

What about a hanging shoe rack to store them in? You can probably get one with less holes in…

You could sell those you don't want on Vinted.

You can stack the baseball caps they will fold in round the peak. I would stick any you don’t want on FB marketplace for free.

Put some key holders (the ones mounted on wood) on the wall and hang on these?

I did think of trying to sell them but most horsy people have got enough themselves and I'm not sure anyone else would want them, as all have logos of some type.

TBH I think a shoe rack would take up a lot of space I don't have, but Fieldlife's suggestion of a key rack sounds like it might work for the baseball caps. I could hang several of them on top of each other, through the tightening strap thing on the back. Thanks!
The beanies aren't so messy as I have them stacked flat, on top of each other.

But if anyone can think of a good way to clear out some of them please, that would be even better!

Take them to your local equine charity if they sell donated tack, I know we would x

That's a brilliant idea! There is a very good equine charity shop near where I keep my horse, I'll bring them along there. Plus, they have a Rescue Farm associated with the shop, maybe some of the helpers would like them to wear. I'll suggest that too.
Thanks for the great suggestion.
