I'd be in for #3
Welcome. A video will be sent to you. It's up to you if you wish to share it with the group or not.
Everyone else has the choice to annoy ezeminer to try to get this hint.
Very Cool... will this note include "multi-tone UV" that you talked about in this video?

Nice find, that's something we're actively working on. The development costs may exceed 0.1 BTC to get this capability in-house. Proceeds of this mystery note will make this possible.
The inks used to make this UV effect are generally restricted for obvious reasons. Mystery notes are a form of R&D for us. The learning process and project funding happens through these notes.

[WTS] OFFICIAL BTC MEDIA HONG KONG CONFERENCE WHALE NOTE UNCUT SHEET
Up for auction is an uncut sheet of the Official Hong Kong Conference Whale notes. The final product will be in the swag bags of every Whale and Speaker at the conference. These notes feature the brand new holographic strip that took three years to design and source. Proceeds of this auction will directly help fund the trip to Hong Kong. Tracked shipping is included worldwide.
The design is marked by the famous “Junk Boat” with the conference center and skyline in the background. The design was custom made from scratch in Engraving format. An evolution and clear quality increase compared to the Las Vegas notes.
The theme of the conference is “the signal”. References to this can be found hidden around the design. BTCs growth is gradual and conventional hype and bust phases are but a distraction.

Am I reading this correctly that you're selling these for $100 under melt?
Re: I'm surprised this hobby and genre of crypto collectibles isn't more popular
The first time I held fake CAS holograms in my hand was in 2022/3. But the way Mikes' holograms were made used some very clever security techniques. Extremely advanced for 2011 and still easily hold up today. The only way to truly copy the hologram would be to have the "master". The physical engravings have encoded info above 10k DPI (probably E BEAM tech so at least 100k DPI) and can't truly be copied to the level where an auction house would struggle to know the difference.
With EBAM, you can shrink an extremely detailed map of the moon to the size of 1cm (https://www.optaglio.cz/en/e-beam-lithography). No scanner on earth could replicate it. Not to mention that engravings are actually 3D. So you'd need to get the right angle of the curves and even the varying thicknesses. Good luck with that.
Document security is typically split into four levels, with forensic being shared with the auction house. The fourth level is only known to the manufacturer.
On top of that, the consistency of the materials and chemical make up create a sort of signature. Like artwork that is worth millions is verified, so can Cas coins.
For example, each Polymerbit can be traced down to the printer, country and day it was made.
I can say with confidence that we've been researching these security risks for obvious reasons. I'm not overly concerned for the future of collectibles.
What I knew so far was that DEFCON hackers had succeeded in removing and replace holograms from the 2012 coins without leaving any visible traces https://www.coindesk.com/markets/2013/08/13/defcon-hackers-crack-physical-bitcoin-casascius-coins
Even if it’s really hard or nearly impossible, we gotta be ready for new fakes anytime.. do you know what series those fake holograms are from and are there any pics of the fake holos
Visible traces are a bit of a misnomer. There's an injection site for the adhesive neutralizer. While it could be argued to look like wear and tear to the naked eye at a quick glance, the valuations of these coins have now exceeded normal circulation and certainly require authentication.
Closer examination is generally conducted by microscope under such circumstances. Perforations cannot be hidden. Even with attempting to fuse the plastic together, it'll warp and the structure will be visible in the right wave lengths.
You may find this thread interesting. I understand why you may feel there's cause for alarm, but the amount of experts involved today reduce the risk.
As with normal numismatics, fakes have existed for millennia. Genuine coins are still identified and generally don't lose their value even with this risk.
As with anything valuable, the sellers provenance is important... and so is forensic verification.
Here's the thread you may find interesting.

I hope this helps you feel less concerned about the risks.
Re: I'm surprised this hobby and genre of crypto collectibles isn't more popular
If this is really true, then it needs to be made public to protect the remaining collectors... otherwise, we are going to get some very serious problems. If it's no longer possible to distinguish between originals and fakes, the entire field is 100% dead. It will die a slow D E A T H. Even coins with a clean history will no longer find a buyer.
Since when exactly have these faked CAS holograms been in circulation ??

I've been collecting a mix of things:
1) Coins (US & World Silver / Gold)
2) Banknotes
3) License Plates
4) Maps (WWII and older)
5) Old books (1800's and older)

Re: I'm surprised this hobby and genre of crypto collectibles isn't more popular
I think it's in the collective interest of our group to introduce more people to the space. Not only for a valuation standpoint, but because we'd get people from all corners of the world.
I'll in Hong Kong (BTC Media conference), Tokyo and Manila showcasing collectibles. We're still very early and it'll take time (and effort) to get there.
Stacks and Heritage are doing the heavy lifting these days. Their exposure is without a doubt positively affecting our group.

Excellent! Now I can post a nice hint.
A 365nm UV light will be included in each box.
Here's a close up shot of part of the bill.
To celebrate the unexpected rise in Bitcoin we're sweetening the deal.
Each buyer will get an additional official BTC Media Hong Kong conference note.
The notes are currently being designed and almost all will only be at the conference for whale pass holders and speakers.

I should add... you have a 20% chance of getting a ____ one instead of a blue one. Only two _____ exist. The offer only counts if pre-ordered here.
Two slots will be randomly chosen and the _____ note will be sent instead.
Questions are welcome if the inquirer accepts the fact that the answers may be rather vague.

I'll bite.... When you mention the note is manufactured using "greater tolerances," do you mean tighter (more precise) manufacturing tolerances? Could you clarify exactly what features or dimensions are controlled more strictly in these new notes?
In engineering "greater" means wider. So early processes are not always as refined yet. For reference, the past five mystery notes tend to reflect that.
These tend to get better with time as we figure out the logistics and applications.
More hints will be given after every reservation from now on.
