Topic: CASASCIUS PHYSICAL BITCOIN - In Stock Now! (pic) - page 55. (Read 130354 times)
I guess I'm kinda worried about durability. If it gets wet will the hologram be destroyed or fall off? What if it goes through the washer dryer?
I was told: "They are solid brass. They are 1.125 inches in diameter and weigh about 7.5 grams. Compare to a US half dollar at 1.2 inches and about 11 grams."
What is this coin made out of ? Plastic? Cheap Metal? Other?
It's really up to you, he's trading a 1:1 value (shipping aside), in my opinion this is a method of cold storage or, as you said, face-to-face trading. (Possibly not face-to-face, if the trades sole purpose was to hide the exchange of a large number of bitcoins, eg. dark net trade.)
If used for transferring bitcoin, it would be awesome if we could send money to the address on the coin. Why is only the first 8 digits on there?
You could try first bits.
That doesn't satisfy me. Another address could've been generated intentionally using a vanity address generator or by chance.

OP plz dont call this money call them wallets, according to some EU laws you cant issue money
While wallet is more accurate, that would confuse the crap out of some people: "What? This is no wallet, dude, I know what a wallet looks like. You put money into a wallet, you know. This is clearly a coin and therefore some sort of money. Bugger off."
Why would you buy this given the current state of the Bitcoin market/economy?
Actually, let me quote a friend, who I explained bitcoin lately: "The 21 Million cap is a great idea and I also like the fact that this is community-based and not some institution. But, why is there no way to actually use these in physical form for normal people?"
This is physical bitcoin money, not (merely) some investment token.
Awesome! How can I buy some? 
Sorry if this is a novice question but let's say I get one of these and then decide I want to use it to buy something online. How do I send the coin to my wallet or another user?
I'll be adding a private key import function to strongcoin that will allow you to import the private key in the mini format.
You'll then be able to spend the BTC.
Well, sorta
Its either 1:1 or its not. In this case its not. And with good reason: As casascius already said, its about sustainability. Something I completely agree with as being justifiably necessary. Aside from this, the reason is irrelevant to the fact -- if its not 1:1, and casascius never suggested its 1:1, then I don't see why the point to argue that it is 1:1 or even 'sorta' 1:1.
You crack/peel it open, theres a 'compressed' version of the private key on it, you'd have to use a tool to run a SHA(minikey) which will spit out the full private key, then you can use a wallet.dat editor to import that by just typing/pasting it in.
It's a little long process right now, but there's more tools on the way and even some proposed for official client for import and export commands!

OP says: 1.25 BTC per coin for up to 10 coins and better rate for more coins.. Not 1:1 though.
Well, sorta, the coins 1:1 with it's loaded face value you traded for it, the extra bit covers the manufacturing and a sort of taxation. Just like a US penny costs what, like a dime to manufacture, mint, and 'sell'? Face value is face value, considering 20% on a really large number of coins would only need bitcoin to succeed 20% for you to profit on the physical version, but if it doesn't profiting from business and transactions would change hands a few times and essentially pay itself off in usefullness with tiny 'invisible losses' to multiple people who are using a slightly more costly coin for transaction instead of digital with that small transaction fee.
The holograms are very tamper evident. They reveal a honey comb pattern if peeled. The adhesive is pretty strong, I have to use transfer tape to get them on the coins because they will show honeycombs if the sticky side even gets grazed by a finger.
Cool, I like it. This would be good info for marketing campaign. Also a little instruction guide how to spot a peeled sticker (like with a little comparison pic or something).

Incidentally, who wants to wager if or when Casascius will be Bitcoin's Bernard von Nothaus?
Thinking of how to word it, and guessing what dates to use:

Thanks! Do you know if this format is any sort of standard? Or is it pretty exclusively used by Cacascius?
It is standard to the extent it is merely a string whose SHA256 hash is used as a private key, something fairly well understood even outside the context of this format. However, I have proposed it as a standard mainly for the purpose of making it recognizable and to allow implementers to offer the built-in typo detection, and because a shortened private key form is universally desirable for similar projects.
Does this mean that each key is loaded with 1 BTC?
Yes.
I can't find anything about mini private keys. Can you link to any sources?

...These are a REAL BITCOIN each worth 1 BTC. One side has a hologram. Underneath the hologram layer is a private key. The first 8 characters of the bitcoin address appears on each coin.

How about spread some fud in the speculation channel and not in someones thread who is actually trying to do something good for the community and actually produced something unique
I hope that doesn't mean that the idea is not open to any forms of criticism. I'm not here to do that though, however I do have some curiosity:
After purchase, are the coins intended to be traded hand-to-hand, as per regular currency? (of course I mean within a community of bitcoin aware individuals). If so, are the coins / codes tamper proof, so that any individual who receives one coin can instantly see that this coin has 1 BTC of value (not been used).
If not for hand-to-hand trading, would it be fair to assume that the coins be primarily for aesthetic and novelty purpose?
