Topic: ANN: 100mBTC (0.1 BTC) physical coins + 5 free coins naming competition - page 4. (Read 11379 times)

Just a thought. I understand why you would want to do this but you may want to consider the implications of your coins being "in the wild" with no assigned value. How can anyone trust your coin if there's a possibility it is not worth anything? I know it would be possible to check the public key but that's probably not a good expectation. You might just be best off assuming that you're going to lose some here and there.

"Phycoin" rolls off the tongue better than "Physcoin". That just sounds like fizz coin.

I actually posted elsewhere that no one would challenge the Casascius brand, anytime soon. Looks like i may have to retract that at some stage!

I like 'Physcoin', and 'Bloccoin'

I would order 10.

Very nice design, I've always liked bi-metal coins. I would also like to put a pre-order on 5 coins, and maybe a few "broken" coins.

Name suggestions:

Sector Coin
Chunk Coin
Bitecoin
Bytecoin
BitPart
Bit Segment
Bitstake
Quantumbit
Slice

Good luck with your project, I look forward to the final product!

The symbolism of the lines and the people wasn't immediately apparent to me, but I guess it works.

As for a name, why not just P4coins?

edit: nvm, brainfart

I may do other denominations later. The most expensive is the hologram, single metal coins are actually quite cheap. But lets see if I can break even with these coins first before I sink even more money in it.


Casascius coins already do that, and so will I. TBH, those holograms seem fairly sturdy to me, I have yet to damage one by accident. I dont have a final design for it yet though, since I dont even have a name . But it will look good . Lead time for the coins is a lot longer than the holograms, so I still have some time.


Backside will have an edge so the hologram sinks in a bit.
The symbolism of the people seemed rather obvious to me? Around the globe people exchange bitcoins directly, p2p. THey are connected by small dotted lines. I think thats busy enough without lat/lon lines.

This is a great idea, and I'd buy 10 or so. It would also be nice to eventually see other denominations such as 50, 200 and 500 mBTC.

One downside of the holograms on casascius coins is that they're much less tolerant of the general handling and abuse that comes from being carried around in pockets and stuff, but I suppose there's not really much that can be done about that. Maybe have the hologram sticker recessed into the coin by a small amount (the thickness of the sticker) if it's not impractical.

Would faint latitude/longitude lines on the world map look good? What's the deal with the people around the edge? What will the other side look like? Reeded edge or plain?

HI all,

Im happy to (pre) announce that in about 2 months I intend to start selling 100mBTC physical bitcoins. Im about to place the orders for the minting and the hologram design will be finalized in the next weeks.  Im posting this here to make you aware and gather some feedback before I pull the trigger.

These coins will be made in beautiful  bi-metal, just like 1 and 2 euro coins and be a bit thicker and heavier than Casascius coins. This is the almost final design of the front:



Feedback is welcome, but its unlikely I will change a lot.

The back will use the same principle as Casascius, with a fully custom tamper proof holographic adhesive covering the private key, while a window on the hologram will reveal the public key, possibly as QR code.

The reason I decided to go ahead with this is not so much to give casascius competition (I have the greatest respect for him and I am the proud owner of a fair number of his coins), its just that I used to hand out 1BTC coins as freebees, but at the current price, even Casascius new 500mBTC coins are rather expensive conversation starters.

Initially I planned to make these coins as cheaply as possible; using cheap aluminum and stock hologram seals with only a lasered public key on the holograph, but it would make counterfitting just too easy. Since most of the costs are NRE and the per coin price is rather low, I figured it should be possible to sell enough to enable beautiful and secure (*) coins that are still affordable enough to hand out. The NRE to mint the coins and produce the hologram is quite substantial, so I have yet to decide on pricing, but Im aiming for as close to face value as possible, particularly for large orders I hope to get the price (excl bitcoin value) in the single digit euro range. This wont make me rich, but for now Ill be happy to just recover the investment.

(*) About security; Ive looked at this from all angles, Ive considered doing 2 factor, but in the end Ive come to the same conclusion as Mike: its just not feasible for small denominations. So buyers will have to trust me that I dont keep copies of the private key and I wont steal their coins. Im banking on the reputation I hope to have among many here that used to trust me with their hashrate, and hoping the smaller denomination and small markup price - making it more likely they will actually be redeemed-,  will make that pill easier to swallow.

I intend to sell these coins directly for BTC but also for a higher premium through ebay and bitmit. On ebay these coins will also be sold for paypal; but will ship without BTC value until the buyer confirms reception. I hope that will provide me with sufficient protection against charge backs. Any knowledgeable feedback on this would be appreciated.

One thing I havent decided upon is a name. I still have a company that my brother and I registered a few decades ago  which was called Foresee. We will likely put this bitcoin business under that legal umbrella, so using that name is one option. But if you have any better suggestions, please PM me your suggestion. If I decide to use your name, I will gladly send you 5 free 100mBTC coins as thank you. Submissions should be sent within a week from now.

I will probably do formal preorders later, once I have a firm shipping date,  but to get a feel for the volume and amount of (dis)trust I have among forum members here, I would also appreciate if you posted a non binding "preorder" below indicating how many coins, if any, you would be willing to buy. Doing so will entitle you to a small discount once these coins  go for sale provided you actually do place the order.

Cheers,

P4
