Topic: The 25 BTC CASASCIUS PHYSICAL BITCOIN is here! (Read 6816 times)

  I have been looking for awhile but never have come across how many blanks were sodl.

  I do know I only came across one for sale thru the years and that is the one that is part of my collection.

  I think they are harder to find than the loaded ones. But I could be wrong.

This is a good question Miner Jones. I don't know personally but I am watching for the answer.

Does anyone know the quantity of blanks there were made/available?
This would be a good figure to add to the encyclopedia since there is no mention of these in there.

I got my 25 BTC coin today...wow...as a hobbyist coin collector, I must say, this one was pressed with gusto...it's more like a mini 3D sculpture than a plain coin...the relief (in numismatic terms) is ultra high. It feels great in the hand...as does the gold plated bar!

Well done again, casascius!

i received this stuff! Very, very good product. Playing with it like a kid now )))

Utah eh,?  R U a mormon?  If so its a deal.  Never met a crooked mormon (except for the ones in politics and Rick Koerber).

Wow, you thought this thru...as soon as some stuff clears i'll buy a few

If nothing else, I think Cassies will be collectable if not museum pieces in 50 years 

In a theoretical sense, I could scam my customers.  In a practical sense, seeing as how I give away my real life identity and have PGP signed the list of addresses I have prepared for my coins, those I scammed would have fairly strong recourse against me.


Sure, if anyone wants to spend four figures to get custom holograms done, only to be able to perpetrate a scam that will probably be figured out in days if not weeks.  It's been discussed in the past.  If someone goes to the effort of doing it, that'll be unfortunate.  Hopefully they'd see it as just as lucrative to generate real legit coins (i mean, I'm already charging a 20-25% premium over face value, isn't that good enough?).  Same argument as it applies to mining: it pays more to be an honest miner, and therefore have reasonable faith that miners are honest.


Buy one, and buy a billy club with it.  If I scam you, come to Utah and beat my ass.  My real address is on my website.  If I don't scam you, you've just given a great gift that hopefully will appreciate.


I deliberately chose inkjet.  Laser toner is relatively thick and can be read from the outside with radiation or ultrasound.  Inkjet may fade in the same sense old photos become slightly off color, but you don't see them fading into oblivion like the photos turning into blank paper.  That said, I used an off-black color to ensure that C+M+Y+K ink all contribute to the color, so they would all have to fade to blank for this to be an issue.

did you select an ink and paper that could withstand the test time?  injet printer ink evaporates.  laser is better...  just curious if in 20 years it would have faded away b/c you used a crappy lexmark inkjet.

maybe i missed this, but how is this coin secured from 2x spend attack.  that is the issuer (Casasious) could also have a copy of teh coin's a privkey.  i know there is a tamper evident seal and a code to check with the issuer its authenticity.

Lastly, how is this secure from counterfeit?  couldn't i just copy the verification code of a legit coin and try to pass one off?  people accepting these will likely not redeem them, so the counterfeit may not have the right privkey inside, but its outer check number thingy would be right...

maybe i dont understand.  but if you can explain this to me i'd love to buy a 25 btc for my 3 year old nephew, just like i've been buying him silver eagles every b-day since.

That is a satisfactory response.

Not exactly.  I'm willing to ship them unloaded and load them on receipt so they aren't as valuable while they're being processed for customs.  But I am not willing to allow them to circulate unloaded.  If they are in the wild, they are either already loaded, or going to be loaded.  Also, any coins shipped that way would be shipped with a method that offers international tracking and a signature, because I intend to load the value whether the coins arrive or not.

I know that when a miner generates, the 50 BTC reward (or portion thereof) can go to a specific address.  Eligius, for instance, does this:
 - http://blockchain.info/tx-index/11312776/f46dd33fe4397cbba04bc7b25560ac3c715c6b4cd1371f61dba04a639cec98a7
As does P2Pool.  Eligius even offered to do this for non-miners on a contract basis.

I think one of these 25 BTC with the 25 bitcoins coming as generated coin would make it even more valuable.  Because there are only about 60 thousand 50 BTC blocks remaining, a pair of these collectibles each with 25 BTC from the same block would make them even more valuable as that is something that cannot be done again after about a year from now when the 50 BTC reward drops to 25 BTC.

Incidentally, I showed the physical 25 BTC coin at my monthly coin collector meeting.  Out of 40 (including many that are octogenarians or close to that) there were four who were interested in these.

From a different thread Casascius wrote:

So just to clarify -- it is possible that these could be circulated without having the hologram tampered with but having no bitcoin funds loaded, correct?  I.e., if I were to accept one of these as payment or purchase one, I should first check the address to confirm it has the bitcoins loaded?

The 25 BTC coin is now available online.

I am also offering the piece for sale with no BTC value for 3.5 BTC.  Of course, it has no hologram on the back.  It looks the same as if you bought the full coin, redeemed the BTC, and cleaned off the hologram residue.

(Consider this:  Even though they won't be true "Casascius Coins", you could buy my blank coins and sticker them yourself with generic 1" circle hologram security labels off the Internet.  Even though you might not be able to circulate them, if all you care is to collect them or to give them to a loved one, you may not care.  This eliminates the risk of mailing real BTC.)

You should sell them on tv ! Remember the $20 from Liberia to commemorate 9/11.

Perhaps include the motto "In Casascius We Trust" 

The papers are what literally go in to the coin under the sticker. So nothing to shred.

Thank you, casascius, for that great explanation. Perhaps you could include some description of it on your ordering page?

I assume the papers are shredded or similar after their keys are put onto coins?
