Figpin Mini Hyper Rare availability?

Hey all, I just wanted to know if there's any way to tell if they still have certain Hyper Rares in stock for the Mystery Minis. I don't want to ebay the 1 or 2 missing Figpins to complete my daughters' set (Iron Sword/Spider for Minecraft S2, and Diamond Pickaxe for S1, if anyone's wondering/can help with that) if the hyper rares aren't actually available anymore. Thanks.
