Hi everyone,

I'm not sure if this is the correct place to post this, if it is not; please, go ahead and move accordingly.

I've been working on a new Casascius tracker tool for the past month or so on my spare time. While it is nowhere near completion, I do feel its at a decent usable and functional place to share with this community and get some feedback. The goal of the tool was to be able to do extensive analysis on Casascius coins, ie. destruction trends, frequency, overall rarity, etc.

Please note, that I will be adding more graphs and features in the coming weeks, so do not be alarmed if you see major changes.

Features:
1. Filtering on a number of metrics
2. Sorting
3. Searching
4. Exporting to CSV files
5. Graphs and other analytical metrics

When I am done refining the tool, I may look into extending the tool to other coins. If there are any suggestions or requests, please include them here. Also, my knowledge of Casascius coins is slightly limited, so I am asking the entire community here for help refine the list further e.g. the infamous double error coins. If you have any information or notice an error in my list, please let me know.

Thanks!
Mel

Like the idea and the site bro! Good job

Very cool tool to have. Well done!

This is a dumb question no doubt but what does 'unused' mean when it comes to these addresses and how they relate to the coins?

Are these addresses published by Mike Caldwell at some point?

Here's an interesting one  :o

https://casascius.ludvigart.com/details/?url=%2F%3Fsort%3D6%26flt0_54%3D10%26desc%3D1&id=5b60e43aa86feb072dcc25c6

1 million $ on a good day ;D

Yes, Mike published a list: https://www.casascius.com/fulllist.txt

Do you got any idea what the thinking was behind publishing them since those addresses have never been used? Were they on scrapped or unsold coins? Or load your owns?

I think there were a few coins that were sold unfunded. Casascius did sell a few Gold 2FA 1000 BTC coins that weren’t loaded (Coblee has a bunch).
I could be mistaken but some could also be from coins that were never fully assembled. You can see the control
process Mike Caldwell used here: https://www.casascius.com/controls.aspx
Perhaps some coins were left unfinished but since the addresses were already generated they were published accidentally.

Mike was forced to shut down operations in 2013, a lot of those addresses never reached production. See:

ULTRA-RARE EXTRA-SPECIAL ERRORS AHOY!  :P

Thanks Dazed!

I'll get these Addresses added later tonight. I'll also begin working on tagging the HardBTC coins.

Edit: After speak with Dazed, I just realized that all of the silver coins produced in 2013 (1Ag) are Series 3. I will also have this correctly tagged.

Best,
Mel

tremendous effort fella, I know how hard you have been working on this.

Very nicely done, I especially like the Destruction (https://casascius.ludvigart.com/destruction/) and Status (https://casascius.ludvigart.com/status/) statistics. Thanks for your efforts, great favor for those collecting these rare coins (and getting scarcer every day!).

Great work!! Can you explain what you mean by "destruction"? Do you mean redeemed?

Feel free to take advantage of provided information (https://nastyfans.org/mint.json) for NastyFans Minted Seats.  You can contact me with any questions or refer to the existing analyzer (http://analyzer.nastyfans.org) as a reference.

Thanks everyone, glad you like the resource!

Thanks :D Yeah, destroyed refers to redeemed. At least, thats how I view them. If this is not intuitive or may be misleading, we can definitely relabel these.

Thanks for this, will do when I am ready to proceed with non-Casascius coins :) The good thing is that the code is modular and extensible so it'll be pretty easy to add other coins with little to no effort :) I just need to get the main one down first.

Updates:

- Correctly tagged Version 3 coins. Please note that some 1BTC Version 3 coins do not start with ^1Ag so it'd be very difficult/impossible to tag them correctly.

- Improved the destruction graph by showing overall growth trend over time.

- Added another graph: Creation graph (this will show
https://casascius.ludvigart.com/creation/

Tonight, I plan to break down the Version 2 1 BTC coins by year (2011, 2012, 2013). It should be pretty easy to do.

Great stuff, thanks for sharing.  This fella should get all the merit for the work done here. So much effort returned to the community at no expectation  of reward. 

Rusbit...great work..only one suggestion...

Can you please change from destroyed to redeemed? Its kills me to hear Casascius and Destroyed in the same sentence. Redeemed is hard to but I can live with that.

Other than that I applaud this work you have done for us. ;)

BTW the graphic makes it so much easier to comprehend it all too.  :)

Thanks! :)

Thanks, appreciate it!

I suppose 'Destroyed' can be a bit misleading or extreme, at least to people less familiar with Casascius coins.

Do others feel the same way? Should I rename: Destroyed -> Redeemed? If there is a better term we can use, feel free to suggest.

This tool is great! I'd like to be the proud owner of one of them, but is good to see this kind of work if someday I decide to eventually purchase one.

The beautiful thing about this community is that many members are willing to develop beautiful tools for free. Keep on with the good work!

 If not redeemed perhaps>>> Swept.....Peeled...Unloaded?  :)

great work, I was looking for a site like yours for some time now! Enjoy some merits :)

There might be destroyed coins out there - physically.  So they no longer exist.
The redeemed coins have a market of their own, they just don't have any balance associated with physical coin.

@Krog
@Canary

Thanks guys for the feedback, I'm going to go ahead and rename Destroyed to Redeemed due to popular demand; you guys are absolutely right.

I'll have this pushed out shortly.

Any chance that this could be open source on Github? ;D

Hi Lauda,

That is the plan after I'm done. My code is very shitty at the moment, and I'm ashamed to upload it to Github right now haha. I need to do some major refactoring and cleanup.

This has been completed! Destroyed has been renamed to redeemed.  :D

And I have broken down the Series 2 1BTC Cas Coins by year.

Type: S1-COIN-1 ->  [ S1-COIN-1-2011, S1-COIN-1-2012, S1-COIN-1-2013 ]

Cool bro. Thankyou for doing this

No matter how you word it a peeled loaded coin is destroyed. 

I vote using 'destroyed'. A peeled cas removes the coin value from it, so no longer a coin. You just have a redeemed token thingy.

Why don't you just do like "Redeemed/Destroyed" with like a popup info thing explaining etc ?  Would solve both problems, right?  :D

Edit I agree with dazed but also with how newbs may construe it.... better to please both parties! :P

The pop up should be a mushroom cloud and a flashing display of he word destroyed repeated. 

I would do that, but:

1) It doesn't work too well in the database, the database will need to store one or the other.
2) There is limited space real-estate, making the column too long will make the table row wrap itself which may ruin the aesthetics of the table. I have to test this out of course.

Nothing is set in stone yet. Perhaps, we can debate and make come to a conclusion. I suppose 'Destroyed' carries a bad connotation and I can see people who have redeemed/destroyed Casascius coins be concerned with such rhetoric. Same applies to the other side. Maybe presenting both words appeals to both parties. I also don't want this to turn political though lol :o.

On the other note, I am planning on creating a page that explains everything to newbies in detail and goes into the history of Casascius coins.

;D ;D

What languages are you using? There might be people that are able to/willing to help. ;)

Everything is Python. The graphs are done via a Javascript library (plot.ly).

Web Framework: Flask /w Flask-Admin module
Database: Mongo

Let me do a bit of cleanup :p and I can get it up.

:'( Why not in PHP?  :P

Haha, I only know Python and Flask is super easy to work with and build web applications. :p

I just found out the tool got featured on this website: https://bitcoinist.com/expensive-ever-bitcoin-casascius/

I'm just a little bummed that sensationalized 'terrible security'.

I see. Ding me on TG if you use it 'GrumpyKitty', I can help you with some server side security.

It's quite known already, well no wonder. Your analytics look better than this: https://casascius.uberbills.com/. You might want to add something like this too: https://i.imgur.com/GflyLHY.png.

Classic journalism. ::)
