Disappointing to see the 10 BTC go for the loaded value. Probably not the best timing given the sentiment around BTC and the broader financial markets.
A long held, but controversial, opinion of mine is that we will see the high load value coins (like the Cas 25 or even 10) trade at less than face value at some point. There are risks such as a private key being illegible over time, the hologram has been tampered with, etc which will be priced in as the USD value of the coins increase.
