Pretty sure
nobody here is going to buy a brass cas 65 in a newer label for 2.5
BTC ...
Maybe an MS69 or 70 but even that's a huge stretch. Good luck tho. Maybe ebay is where you want to go for this price?

With the ease of transferring between USD/EUR/GBP etc into BTC it only makes sense to think of the premium in terms of fiat. If BTC were $1mm the premium would be so small it of course will be better to just peel. If BTC goes back to $100 then sure multiples of the BTC value make sense. I dont really feel bad for those who paid a large BTC premium for these coins years ago because they most likely paid small $ value for the BTC at that point. Either way they are still ahead. The only person who would get burned is the one who thinks paying large BTC multiples make sense now with BTC where it is at the moment.

Still 20k active Cas, compared to 7k redeemed Cas. As that drops, and as more high net worth individuals discover bitcoin, I expect the premium in BTC will start to climb again. Eventually it will get very high. All that being said, collectors or any type of coin value high grading exponentially more than average, so whilst a MS69 might get x2, an MS65 would only be 1.2x.
Quite possible, but unproven to date, and
many get peeled all the time, still. Until more collectors with deep pockets arrive here, or they are recognized in the numismatic community more, it may be a while...
Edit - looks like it's at 10k redeemed or so:
