I guess i forgot that it'd be far less secure if i gave away the physical coin =P
Good to know all of that, thanks =D

Can the guy return the bar back to you for a reload
Yes, about $5 plus BTC.

I don't do vanity addresses with holograms, sorry.
If I am in the process of generating a batch of addresses, I'd allow selection of the addresses from my batch. Remember, these use 30-character Minikey, which there is no way to vanitygen quickly like full keys (other than for selecting maybe three or four characters). It is difficult to fit 51 characters in the space allotted on my coins.
The way I do these, is I format a blank hard drive, install a fresh OS, securely generate a large number of addresses, print them, and then trash the drive. I believe it's reckless to do anything less. Then I laser cut the circles and put them in jars according to what kind of coin they'll go on.
Once the laser circles are cut and put in jars, it's practically impossible to find a specific circle, the jars are full of circles mixed as randomly as a bingo ball machine (but with thousands of balls!). (One repurposed Nutella jar I use for 1BTC circles seems to hold about 12,000 circles). If I know to pick a circle out before I cut them and mix them, that would be different. But now it's too late, I have enough private keys to last me a long time and I have no plans to generate new ones any time soon.

First i know this is about that 1000BTC Bar, but i'd hope it would apply to it too.
Casascius, is there anyway to give you a private key / public key to use to make a coin, 1BTC. I'd like to use a Vanity address

Casascius could offer that as a service - he could generate a special vanity address according your mask for you for a premium.
Yeah that would be interesting & secure.

He won't give you a hologram because you could "cheat". You can buy blank coins and make your own public key / private key sticker. Given it would only be used for you there is no need for a hologram likely an Avery label would work fine. Just get one the right size.
Wow man, very nice!
You should make one of solid gold, because soon the value of those 1000 bitcoins will be more than the value of the solid gold by at least 100x

If I engrave into metal, that deforms the metal. The engravings can be read simply by aiming any sort of radiation at the coin that the metal reflects and that the covering lets through, and then looking at the reflection. This is why I went with plain ink.
As a proud owner of a dozen original casascius coins, I'd like to say you're moving in a great direction. Could you laser engrave a private key into a gold card (securely)? That would be the most permanent offline wallet.
Anyhow, great job once again!

Looks like the guy just paid a big premium to just get the bitcoins inside.

Maybe because it's an 'easy' way to get bitcoins with a CC (or stolen CC)?
I can't think of why else you'd pay a premium like that just to open and use them right away after buying such a cool item... the bar itself I'd think (this early in the game) should sit around as a cool talking piece.
It's my guess, who knows.
I love the look of that gold bar *whistles*
I wish I had 1000 to toss around
Shit you might as well make a 10k one and a 100k one.. just don't load them until you get a serious buyer.
The 100k one, should you ever do it, should be solid gold [edit: I mean like one of those solid-gold bars like you see on TV of Fort Knox]

you should've made it with 10x the gold of the 100BTC bar.
It has an appeal for being cheap: it's a plausible way for someone to buy 1000 BTC for credit card but still be buying a tangible good, for the lowest possible premium.
Increasing the gold content would drive up the price.
I am getting more inquiries about the 1000 BTC gold coin idea. I discussed it with the factory who did my silver coins. I might seriously be able to do it for $200 over spot price (of both BTC and gold), on a fully-refundable-deposit pre-order basis. It costs a lot to do a small run of custom gold coins, but at that price, it's also not ridiculous given the total price of the item.
You need to make it stackable. That would be awesome.
Its a flat rectangle, what part of it isnt stackable ?

Hey Mike,
