Thank you for the reply. Makes sense that people would go for the BUNC version when they are released the same time as the Proofs. I noticed they haven't done the same for the Queen's Beasts (my favorite series). Personally, I only collect coins that are made of precious metals. I can also see how these coins are a risky and the mint can make errors. Mine had a blue plastic on them, that didn't impact the quality of the coin, and luckily fell off when NGC put them in slabs. The rim looks very delicate as there is an engraved notch on them. The details are SPECTACULAR.
I was fortunate to get PF70's on both of mine, but I suspect if I ordered the 2nd in the series I wouldn't get the same now that 95% have been bought. I'd likely get the end of the minting or even returns people made to the Royal Mint.
On a positive note, I have the only ones graded by NGC both in PF70 ULTRA CAMEO; sequentially numbered. I will cherish them for a long time, unless I get an offer I can't refuse.
I shared the pics for both from NGC below so others can enjoy these coins and see what they missed out on. The contrast of the Rose Gold/Gold & Gold/Silver (especially on the Queen's side) is spectacular.
