See message #16 in this thread for instructions - to accept a commitment, I need an actual payment in BTC equivalent as of the moment you sent the payment.  Thanks.

Update: Deposits received for 3 shares.

Also, now that BTC price has come up a bit, I am thinking of placing an order for 0.5 BTC coins.  These would be the same as 1 BTC coins, but slightly smaller diameter (but still big enough to take a 1-inch hologram).  Any interest?  Those would take several weeks to produce as well.

I am trying to convince my business partner to go in with me on one or two shares. Don't think this pushes us over the $3,000 minimum, though, but it's much closer.

I emailed Tony at Bit-pay who mentioned he was pretty sure he wanted a couple shares.

I only need 3 more shares to get the minimum to start the order.

We are about to lauch the cards: https://bitcointalk.org/index.php?topic=64980.msg762894#msg762894

Have you heard from the others ? Could'nt we just have the current order shares increased so we get the order started?
If that's not possible, I am afraid we will have to drop out and source the stickers elsewhere as we cannot wait much longer than beginning of March.

I've only committed to 1 share - but will go in for more if we're close.

How do you print the public key on the sticker?
Can each sticker be customized as to guarantee the customer where it came from?

For example, Let's say I made my own paper currency and used these stickers to secure the private keys.
Then my currency takes off because everyone trust that I, the issuer, is honest and will not still still
any bit coins; however, the con on the internet sees an opportunity to steal some coins and duplicates my stickers and currency.

Do these holographic stickers have a solution to this?
Maybe the only way is to spend the money to buy my very own stickers like casascius did.

I am interested to put $500 dollars towards the project to help get it off the ground.

My understanding is that there is a windowed section in the sticker so the public key can show through.
(lasered in at the same time as your custom text I think ?)

I have refunded 2 of the shares just due to the length of time it's taking.  But 1 of them is still "soft committed" meaning if I hit him up, he says he would probably go for it.

Anyone who wants to make a $500 commitment is welcome to.  I promise to refund it upon request at any time up until the point I pull the trigger on an order.  Ironically, the refunds I gave, received more BTC in the refund than they paid in the first place, due to my insistence that I am accounting for the payment in dollars =)

TO answer your questions:  The public key is not printed on the sticker.  Instead the sticker has a transparent window.  You put the sticker so the firstbits are visible through the window.  All of the stickers are laser-branded with your name at the factory.

I would be willing to bet that it's actually more economical to make coins with holograms than paper currency.  This is simply because on paper, you have to hologram the front and the back, in other words, use 2 holograms.  And you have to use a somewhat big hologram to cover a QR code while keeping it peelable (costs more - cost is directly proportional to surface area).  If you got to use 2 of them on paper, and only 1 of them on a coin, and the hologram costs as much as a coin... then you're actually ahead making coins.

You are more than welcome to look for your own stickers.  That's what one of the guys did whom I refunded (though he had a different application - prepaid cards - so he was able to kill a couple extra birds with one stone by doing so).

That's true, it is testimony to your fairness Mike. And also to the fact that bitcoin exchange rate is still volatile  Wink

Question: can the stickers be serial numbered (with a range of sequential numbers) for the same price ?

Is this offer still good?

How many commitments are lacking for the deal to go through?

I am not trying to aggregate any orders anymore, but if someone had a serious interest in committing enough resources to do the whole thing, and were willing to push it forward assuming nobody else was going in on it, I'm sure it would be easy to revive.  That artwork design is surely sitting somewhere, and for someone willing to fund the whole thing, could have new artwork more personalized to them.

I suppose the fact that I've released the paper circle generator as open-source is a game changer...
