Topic: [INFO] The Canary Thread - page 2. (Read 2908 times)

Thanks for the many detailed pictures of the individual coins. Has anyone happened to document a photo of a peeled Cryptolator Unchained Coin (https://wiki.coin.community/Cryptolator_Unchained_Copper_0.1_BTC) and the condition of the key or infos to the key format and used paper?

Jampacked update coming in two to three months. We're only just getting started with this thread!

Going to start an "outliers" section with some spare coins (these will have their private keys exposed to the elements moreso than the coins in the actual experiment)
- 2013 Casascius 1BTC Brass Series 2 Coin
- 2013 Casascius 0.5BTC Brass Coin
- BTCC Mint Black 100k Bits Poker Chip (the one in the OP will be being switched for one peeled late December. The chip in OP is coming apart so I'm not happy using it any longer for the Canary portion of this thread)
- BTCC Mint 2018 V-Series One Tenth Bitcoin

Also, our first ~6month comparison of the strength of the ink/paper of all the coins listed in the OP right now will be available.

Great,tks for sharing here.

This is an amazing thread! Just discovered it.

Will be peeling a MoonBits chips soon and create some photo footage from it. Can send ship the peeled one to you for further investigation (under a mircroscope for example).

Good to hear nubbins. Loving the community involvement that everyone is showing. This is going to become such a big question mark once we break out into the mainstream collectibles community and we are paving the way to being able to answer the big question of "Are the bitcoin still on this coin?"

I peeled another from the same series that was stored in the same location, and the holo peeled cleanly. FWIW!

amazing workw. it's interesting you can add a cryptoart to the investigation

Just redeemed a 2013 1 BTC Casascius
Key in perfect shape, no decay of any kind

Photos of private key below. Ink is fully intact. Some brown discolouration on the edges. Doesn’t appear to be any adhesive on the face of the paper.

I've peeled the 2013 1BTC Silver/Gilt (already in thread) and a 2013 0.5BTC Brass that will be added to this thread with the next update and have not noticed the degree of adhesive you are finding in the private key recess on either coin. I actually happened to be right around the peeled coins when I saw you posted here and have taken these current pictures for you.

 

Things I can completely throw a guess at would be:
Humidity or heat causing some of the adhesive to run down underneath the insert

An application error by Mike Caldwell? Pretty monotonous applying holograms for hours and hours or even days on end. Of all the coins peeled and shown here so far this might be one of the first to have shown this sort of error application made by the creator.

There just doesn't seem to be any pattern or clue to the splotching pattern it ended up leaving.. this is definitely mind boggling because that adhesive should not be there at all. I'm interested in seeing the private key paper if you'd be willing to share with me even in private nubbins. Completely up to you but that is my main concern and why I created this thread and project.

Regardless of everything the paper splitting in two and being extremely thin should scare everybody. Trying to think of ways for if the thin layer that held the ink remained on the coin face down still... what do you even do? Should always have a scalpel or sharp/fine razor nearby when peeling, also if it starts to tear like that I'd personally try from the other side of the holo and hope that that side of the paper insert remained as one.

Glad you were able to document and share this peel with us nubbins.
Put an X on the board for paper inserts. Engraving looking better and better after every scary peel.

**Edited post, didn't like original reply.

I peeled a 2013 Casascius silver today and was horrified when the paper containing the private key started to separate. I managed to get it off and found what appeared to be adhesive on the silver under the paper.

Very worrisome and I am considering peeling the rest of my collection.

Bitcoin All Time High Bump
Looks like a lot of new and old eyes coming back to the forum recently with coins. Ever wonder what's under your hologram?

Should have a pretty major update with new coins/cards/notes towards the new year, if not shortly after. Lots of coins in the post still on their ways to me.

    Yep...will do so tonight and I bet that it will pass with flying colors. I will place for 2 weeks...test and place and leave in the glass for a loong time and every few weeks will test and place again...and on and on 

   This paper is unbelievable..I cant even rip it, yet you can cut with scissors easily.

  

@krogoth - thanks for the top tips on the Terra Slate paper 
Just an idea - have you thought about immersing the paper for something like 2 weeks , ie, if you were on holiday for 2 weeks and you had a flood ? This would probably be the max amount of time any paper would be under water ? Might be worth a test 

  
    Edit: as per request from Mbitr  will do as follows>>  I will place under water for 2 weeks...test and place and leave in the glass for a loong time and every few weeks will test and place again...and on and on  

Notable post by CryptoImperator that I would like to have documented here for future discussion about Crypto Imperator coins.

Now I get your "Looks at drill" gag on a recent Kia auction thread.
Your project is BTCalls!

Here’s a perfect example why this project is well needed.. if you can help with the project, plz do !




( reminder about Infinitum- https://bitcointalksearch.org/topic/m.34158136 )

It’s a valiant effort, teeGUMES - thank you for sharing and for your time in doing this… I’d like to donate a Kialara Original back to you or whomever donated this one to be destroyed. Just PM me a mailing address.

I thought I'd add: In my latest release; Messengers, and because each bar features a non-replaceable one-of-a-kind work of art, I believe there to be a chance that none may ever be ‘redeemed’, or if they are, it could be far enough into the future that it is critical the private key is legible for generations. And that’s why I added inside of each a backup copy of the private key hand-written in pencil - because charcoal won’t fade, basically, ever.

Here’s the test key I made. It covers the front and back of a small square of museum quality archival paper which is then laminated.



Best,

Max-

Let me preface my answer with the fact that I am not an expert in any field associated with ink or paper, just a guy with a microscope and an idea for a thread.

The first part of your question is exactly what we'll be testing here. Everything unpeeled should technically last longer than the peeled coins on display here. It really starts to come together when you have the data that we already have with the Casascius coins I currently have. 2011 | 2014 | 2020 peel dates and they all look like they were peeled yesterday. Mind you they were all stored in an "unpeeled state" with the private key insert facing the metal and the hologram loosely reapplied to the best of the once-peeled adhesive's ability to hold it down. I've been thinking about this and I have a 2013 Casascius Brass 1BTC on its way to me in the mail right now. I am going to leave the insert and hologram facing upwards like you see in the third picture of each coin here just as a side project.. I believe the more data we have out in the open will benefit the whole Collectibles area. I might do this with a few popular duplicate items, have an "Outlier" section of this project.

Laminating could prove beneficial but there are always the different pros and cons with each new step added to making coins. You may extend the life yes, if you choose the right laminating material.. as we've seen with different top loading sleeves we never really know whats good and whats bad until something really bad happens. You don't want to be the coin maker to find out whats bad.
Also with laminating I feel like the dimensions of your paper insert now change. Thicker, taller, wider.. this now means less hologram to metal ratio which makes your coin more delicate and prone to a hologram coming off on its own. You solve this by making your paper insert smaller to compensate.. but now your private key or QR code is printed smaller and tighter.. more of a chance for the ink to bleed into an unrecognizable format.

There are just so many "what ifs" to think of, I think being a coin creator today you have to look back and just see "what works" and focus on increasing security rather than trying to reinvent the wheel.
Now speaking of the wheel.. is it really a paper insert that relies on the lifespan of paper and ink? I'm already thinking about six months in the future when I pull all these coins out to throw under the microscope again.. the question already in the back of my mind is do I really have to scope the engraved coins**? Something to think about.

**of course I will


Side note: I'd be very interested in an experienced tattoo artists' opinion.
