If I were you I'd be speaking with a high end auction house here... I mean you're talking minimum of $1m valuation. Given the rarity it's probably more in the region of $3-4m and perhaps as high as $10m if done through the right channels.
I.e. the buyer will want legal assurances you have not somehow got the private key from the thing, perhaps independent inspection.

It's already been proven you can take the hologram off of a casaius coin and reattach it with only a pin prick on it being able to tell.

KY Jelly, where has this been proven? And...is it the older holograms he used, the ones I believe they hacked at DefCon?

If you already knew why did you Ask? :p

There is the link incase anyone is interested in the read.

I didn't know for sure that's what you were referring too. I also wanted to point out that if that was indeed what you were referring to, that it doesn't apply to all Casascius coins.

Chi Which ones do they not applied to? The ones that were lasered around the edges or were different cas holos that are more subject to this kind of attack?

The melt ring on the holos, like the silvers have, prevents this attack.

I figured it was the melt rings that helped just didnt know if the series 3 holos had any different adhesive to further prevent this

Terminated.

Excellent question...I just faintly remember reading something about Mike changing his holos after that DefCon conference where it was "hacked", so it couldn't be done going forward.

Doesn't really matter. Incentives prevent this from being widespread, and thus it will never be a real issue.

I'd like to think that nobody is going to drop 7-figures on a Cas coin and not inspect it for track marks...

What would be the deal with provenance and liability? I presume that would be their number one reason for turning something like this down. It's not as if they'll have a Casascius desk. The entire valuation hinges on what's behind the sticker so it looks a little too hot to handle for them.

Do you know this for sure? I'm not so certain EVERY auction house wouldn't touch it. This is what those businesses do, sell rare and unique items. They take a % cut, so if the value of the bar dropped, either way they're getting their cut. I'm not so sure they can be written off so easily.

I've never seen anything like this for sale in such places. I would've thought something would've popped up somewhere by now. Perhaps it doesn't occur to owners.

Fees could turn out to be a beast too.

It's going to be a long time before established auction houses want to touch stuff like this. If you turned up with one now they'd pat you on the head and tell you to leave. Too many unknowns for them and they wouldn't know how to market it either.

If I owned something like this I'd be pretty stumped. I'd probably only sell in person to someone VERY established on here and even then peeling would look like a lot less trouble. I'm more interested in my own well being preserving than Casascius heritage.
