Looking For Some Recent 50p Commemoratives

I'm a collector from the United States. Nothing fancy. I'm putting together a type set and I collect some other random stuff.

I was introduced to the UK Royal Mint about 6 months ago when I purchased the 2021 UK £5 Silver Proof. A very beautiful proof cameo of the Queen. And she's 95 years old!

Since the 2022 Jubilee coins came out, I've been trying to acquire the 50p silver proof with the "70" design and the Queen's bust on the other. I'm spend a lot of time trying to track down this coin. The more common one has Her Grace riding a horse. There is a two-coin set featuring both but trying to find someone to "break" their set is impossible.

And just recently, the 50p UK Pride silver proof sold out instantly. I had been waiting for this coin and well, it was sold out on the day/time The Royal Mint had told me.

So, those are the two coins I'm interested in. Please let me know if you have any leads. Thanks!
