The Casascius 1oz 10BTC Silver Round (w/ Gold B)

I have decided to create some real physical Bitcoins.  Here's what's to come.  Cost: 1.15 BTC + shipping, with bulk discounts available.

Each coin has a private key embedded inside worth 1 BTC, covered by a custom Casascius hologram.  I'm just waiting on the holograms, then these are ready to go!  I will have the ordering website available when they are.  I can hardly wait to see them, they're supposed to be gold and have, among other things, a giant sparkling golden B logo in the middle.



Diameter: 1.125 inches.  Material: brass.  Price subject to revision with Bitcoin price fluctuations.  The back side is flat for the hologram, except for a small circular well which holds the private key.  The first 8 characters of the public Bitcoin address are visible on the outside, pre-printed on the hologram by the hologram manufacturer.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online. Use paper wallets instead.

Hey, casascius I'm a big fan.  I think we are the two first people to have bitcoins in our head.  I have a question though.

How is the public key displayed?

The value of bitcoins is not a theory, predictions of it's failure are what is theoretical.

thought your paper wallet was pretty cool.. this is better.  I think you will do well. they would be good to give out to get people into bitcoin.
I dont know if you have, but you should either develop of link to one of the apps that make it easy to add keys to your wallet as i take it these will have to be broken open to put online?

it would be nice if one day they had something like a micosd card inside that you could just insert in a phone or a pc reader and point your wallet at it and go.(noted that would make them much more expensive)

Still I think these will sell well. It would be nice to see if some of the merchants who have adopted bitcoin will take them.

casascius,

the correct Latin phrase is 'vis in numeris' (not vires).

Price subject to revision?  So a Bitcoin will be pegged to a Bitcoin of a different value?  So, one of these Bitcoins that is worth 1 BTC can also be worth a different amount than 1 BTC?  This is all getting very confusing.  "Hey!  I have 20 BTC! They are worth 15.5 BTC!"

Call me dumb but i don't get the hologram/private key thing...
If the coin holds the private key, what prevents someone from reading it, sell the coin, and move the BTC away after it's sold? :-/
Can someone explain please?

http://www.google.com/webhp?q=%22vis+in+numeris%22

Google is not able to correctly translate Latin Smiley

I've studied Latin in high school (5 years) here in Italy and my wife teaches Latin in high school.

'Vires' means 'soldiers', 'armed forces'.

When used in its plural form 'vires', it may mean 'strength', but only in sentences like 'vires defiunt' which means 'I'm becoming dizzy' (my 'forces' are going away, literally).

If you want to correctly translate 'strength (is) in numbers' the Latin for it is: 'vis in numeris'.

It was even used before, see:

http://articles.latimes.com/2000/dec/17/news/ss-5286

or a manuscript

De numeris: MS Hannover, Landeskirchlichen Archiv D 10 Nr. 1 (PfA Bissendorf HS 20) ff. 186r-195v [inc: Quanta sit vis in numeris noverant...

"How much strength is in numbers ... "

spiccioli.

Its just a single hop. Once it's revealed, you would want to withdraw.

So is there a discount because of the shoddy translation or is it a "collectible unique" now?

Upon reading this thread, I came up with another brain-fart. What if there was a physical Bitcoin designed for each country?

  • USA: Eagle
  • Canada: Loon
  • Turkey: Fez
  • France: Duck!

They would have to destructively tear off the hologram to read the key. These holograms tear in a tamper evident pattern.

Companies claiming they got hacked and lost your coins sounds like fraud so perfect it could be called fashionable.  I never believe them.  If I ever experience the misfortune of a real intrusion, I declare I have been honest about the way I have managed the keys in Casascius Coins.  I maintain no ability to recover or reproduce the keys, not even under limitless duress or total intrusion.  Remember that trusting strangers with your coins without any recourse is, as a matter of principle, not a best practice.  Don't keep coins online.

I think there will probably never a need to tear off and read the key. These coins hold value and are meant as a physical btc exchange medium. Once the BTC is revealed and withdrawn, these coin's only value is its artistic+metal value. Thought there should be a way (like a serial number), for the holder to verify through your website, that the coin is not easily counter-feit and the key is valid.
