I would but it does not store any BTC or cryptocurrency value.
Love the video on the site, their list of 28 items about Bitcoin:
Quote
1. Bitocin has no intrinsic value.
Wrong... Bitcoin is the monetisation of proof of work.
I feel like a broken record; people keep saying this and it shows they've not done their homework. Doesn't strike me as a good foundation for the other 27 arguments they want to build from this first point.

Awesome list No_2!
I will be adding it with pictures to Coinosphere.

That's a great list. Bookmarked.

Added images of a 0.5 silver with a series 2 back. Does anyone have scans of a 10BTC silver casascius coin back and front?
We're going to need one of the plain silver and one of the gold plated one if anyone has them.

Awsome list !
Great collection of photos! Nice work!
My best explanation as to why there would be discrepancies in the two tracker sites has to do with the following:
1. I understand they scrape data from other sites and may not do it consistently, there could be bugs.
2. Although it's simple and straightforward to monitor an address for 1BTC to appear ("funded") and then to disappear ("spent"), there is likely to be differences between the way the two sites interpret balances on self-funded bars, the "roll-your-own" addresses I sold in the past, and the relatively frequent cases where people add extra funds to their coins, reload them after redeeming, or otherwise keep a non-zero balance on the addresses after opening them.

Is there a more canonical dataset (that is easily human readable) than the two tracker sites? This listing is concerned with the coins that were minted, not with how many remain.
Did you mention having plans to make all the PDFs/images of your scanned coins publicly downloadable? I wanted to try get some images from your site too if you have.
Missed this. Good stuff No. 2. 
Nasty Mining:
2014
BTC – One troy ounce silver coin, 39mm diameter, 500 minted. Engraved public & private keys, tamper-evident security hologram with diffusing insert, entirely visible sequential public vanity addresses (all starting with 1Nasty). Each coin entitles the holder to 1 NastyFans share and receives its equivalent voting rights on NastyFans.org and mining operation pay-outs sent to the coin's address. NastyFans has issued 25,000 shares (referred to as seats). As of Jan 2014 each share receives the total amount of crypto mined in the mining operation (at 450GH) divided by 25,000 shares on a recurring weekly basis. This will soon be bumped up to 10THs plus 25MH/s of scrypt power to be added to the mining operation for shareholders. In addition to payouts from the mining operation shareholders also receive a top up from non affiliated users mining in the NastyFans altcoin mining pool where users are currently mining at 750GH/s.

Thank you for this!
I really like your list, and give a thumbs up to the pics!
To bad about what happened to Casascius, one of my favorite minters. (By that I mean the feds, and that stuff.)
Keep up the good work!
p.s. I personally wish that all altcoins had a physical coin, for collecting purposes, and are all of the mints on this list still active? like bitbills for example? (sorry that this is dragging on...)

one small mistake: the photo of the backside of the 1BTC Casascius silver shows the 0.5 BTC coin

Thanks; have originals for those so can fix that no problem. Must just have left two of the 0.5 backs in by mistake. Will fix shortly.

Does anyone have the front and back scans of a series 2 casascius 1BTC coin dated 2011? I could make a set of images up but would prefer to use a back with actual public key that's correct for that coin type.
Great collection of photos! Nice work!

Awesome list. As a collector I really like this.
Sure, the NFC tag will have the full public address and a confirmation code (10 alpha-numeric characters). The full public address will be useful on its own because, as we currently see, FirstBits is non-operable on blockchain.info (unless they fixed that recently).
The confirmation code will be generated by hashing the public address and performing some trade secret set of other data destructive algorithms to come up with the 10 character code. Nothing fancy, just increasing entropy. So my app will ping my server with the full public address and the confirmation code and the server will perform the transformations and verify that the code provided is the same as the code generated. Once verified it will ping other services like blockchain.info and bitcoinaverages so you get a nice "one sheet" of validity and value for the coin.
The security is mostly about verifying the coin is not a counterfeit but I put in a few more helpful functions.

So each time a coin generates a code is it the same or different?

If I get funded my first run will be for 15,000 coins.

Thanks for this it looks very interesting. Can you tell me more about how the Embedded NFC tag security will work? What data does it provide?

Since you have an up and coming section I wanted to post here. I am attempting to start a physical bitcoin that is specifically designed to be traded and not kept as a collectors item. I am trying to raise funds with an Indiegogo campaign. Here are some relevant links:
