As far as I am informed, Sunday’s attacks on silver Casascius Coins left behind evidence of tampering and were not ruled a successful defeat. That said, they only had one coin and chance. It’s entirely possible that, given multiple chances, they’ll succeed, and I intend to give them more chances. This, of course, was true […]

I have been informed that someone was successfully able to compromise the hologram on a Casascius Coin this afternoon at Def Con 21 in Las Vegas. Having been a regular attendee of Def Con for some time now, I figured it was a matter of time before I’d have the honor of being a subject […]

Funding Status: I’m ready to fund, with the exception of 1 Express (postal) Mail package destined to a customer in France where we inadvertently omitted the postal code, and which seems held up in transit near the destination. The destination is still distinct as written without the postal code (Google Maps has no trouble finding […]

Update as of July 28: Private keys have been generated and printed for silver coins beyond the first 32 rolls (of each type). The addresses all start with 1Ag. This will get the orders resuming for rolls 33 and up. Thanks for your patience, some of you have been waiting over 3 weeks. A total […]

Current status on silver coins: We have produced through roll #32 of 1BTC coins, and roll #32 of half BTC coins (64 total numbered rolls). In addition we produced 45 half-BTC coins with the series-2 sticker which were not numbered into these rolls. These were available to those who made initial orders, though are no […]

A common point of confusion that comes up: I’m frequently asked about “firstbits”. Often, I hear people refer to the 8 characters printed on my coins as “firstbits”, or I hear from people who worry that someone might claim the “firstbits” of their coin before it gets funded, or that they were unable to verify […]

Just a quick status report on silver coins. Some of you have received your silver coins. Others, I’m still working on them. Actually, I should say we’re still working on them, as I have someone working full time to help with production and shipment. A short round of applause for Natalie! We have had one […]

I’m pleased to report that I’m selling silver coins again.     I am now taking orders for Silver Bitcoins and Silver Bitcoin Halfs: 1BTC on 1oz silver, and half a bitcoin on a half ounce of silver. The 1oz coins come in mint tubes of 20 coins. The half oz coins come in mint […]

I am caught up on production to the point that I can now deliver a roll of 1BTC or 0.5BTC coins within a couple days of an order.  I am now offering FedEx, delivery times are much better worldwide than with postal mail. Silver coins are currently in production! Also, when I run out of […]

When you order a 2-factor item from me, you’re protecting it with a passphrase.  The 2-factor system ensures that nobody (not even me) can redeem the value from the item unless they have the passphrase.  That begs the question: how can I (as Casascius) create a 2-factor item for you (as the buyer) if I […]
