This coin is still available.

I'm selling a 25BTC Casascius Series 1 (error coin). Coin is fully loaded.

It comes with a digital certificate of authenticity consisting of a PDF scan of the coin signed with the makers (Mike Caldwell's) Adobe key.

It also comes in its origonal pouch. The coin has been untouched since receipt. See photos below, photos are of front and back, in good light, and also with with flash to try show details of the coin.







At this point I am trying to gauge market interest, so serious offers only. BTC or MaidSafe payment only.

So I have a firm offer for a larger amount from a contact I have dealt with before, so I'm going ahead with that. It has all been agreed, just sorting collection times etc.

If it falls through I will post back to this forum and re-open discussions.

Many thanks everyone for your interest.

Yes, absolutely, the buyer gets a copy of the PDF with the signature. They'll need this to prove authenticity down the line.

So from what I understand of the Adobe keys; they are issued by Adobe and can only be verified on Adobe PDF readers. If you use a 3rd party PDF reader then it will not read the signature and just show you the scan.

Different versions of acrobat show the signature in different ways. Some times you'll have to check via a menu option, other times it slaps a dialog box over the top of the image of the PDF.

The PDFs in the .zip have been edited so have lost the signature info. If serious buyers want to send me their email address in a PM then I can send them copies of the signed PDFs.

Mike Caldwell's key he used to sign it was from his swipe clock business [EDIT: the early PDFs were signed with his swipe clock Adobe Key, later versions of the certificates, and the ones for these coins, were signed with a casascius key he purchased specially for the coins], and also shows his name. Each key has to be purchased from Adobe with proof of ID etc and is only valid for a year at a time, so an expensive and arguably secure process.

I also asked Noah at Lealana to do the same for his coins, I understand he offered scanned signed PDF's a few buyers aside of myself in his first year of opperation.

Just wanted to clarify a few things.

The coins have all been taken out of the paper tube the came in have been put into coin capsules to protect them from the air. This was done immediately upon receipt. They were not touched by hand during this process, but obviously Mike Caldwell at Cascascius may have handled them when he made the coins up, though these are from the last batch ever made and he started wearing gloves to protect the coins for the later batches. Please see the photos for details of each coins condition. They are basically as mint as they can be.

The certificates of authenticity are not PGP (though Mike did offer these to some buyers in the early days). They are the later style of certificate, an PDF of a scan of the coins, whcih Mike made and then signed with his Adobe key which is registered to him. Please take a look at the certificates included in the pack I made available to download.

I've also updated the title of the thread.

Based on previous sales, the BTC price dip, their unusual mint condition, and digital certificates; I'm looking for around 47-52 BTC for the lot.

If there aren't any parties or group buys interested in the lot I could split, but would prefer a single sale if possible.

Coin has been untouched and sealed since receipt from Casascius. Sadly are some marks pressed into the label on the back of the coin. I have checked it under a microscope and the label is unbroken, so superficial pressure damage. Please inspect photos for more details.
