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.
From the buyer's perspective, I get it. But from the seller's perspective, it doesn't make sense to sell under face value, unless he
knows it's been tampered with. And in that case, it makes no sense at all for the buyer to buy it. Long term, I wouldn't be surprised if loaded collectibles can't be sold anymore. There's no reason for the buyer to trust it if the seller accepts less than the loaded value, and there's no reason for a honest owner to accept less than the loaded value.
I imagine most of these will just get peeled by the owners... no one wants to take a loss be it fiat or crypto
