A year and a half ago, i had paid and asked wc in this forum to manufacture the dual cryptocurrency but product was not delivered.
This coin was finally made a reality after 2 years. Only one made for 2016.

Oh my..  :o

That is an absolute beast of a coin, if you could even call it that - more like a plate ;D

~20 Troy oz of silver?! Precious gemstones... You went all out with this OP ;D

Well, this should be interesting to say the least.

You need to set some rules for your auction, start time, end time, bid increments, whether bids must be in both BTC and ETH? Also if this will end at a fixed time, or whether bids in last x minutes of auction increase duration by x minutes. Escrow available with a trusted member?

On that note, good luck with this!

Wow  :o

thanks  ;D the production cost for this coin is very high. yup, ~20oz of 999 silver. a larger amount of silver is needed to conceal 2 private keys(btc+eth) easily, though a smaller sized coin is still possible and more challenging.
Bids will be in BTC for ease of bidding.. start time would be now. Would update the other rules later in op. Escrow is available with trusted member.

Also, I suggest not having the auction here but to rather have it in the actual auctions subsection since people can edit their bids here.  :)

How does the redeeming work? Do you need to remove the gems?

this looks really awesome :D

redeeming works the same way, e.g. as visiting blockchain.info and sweeping your btc private keys. Yes, you'll need to remove the gems to retrieve the physical private keys hidden inside.

noted and thanks.. I will hold the auction under the auction thread.  :)

ok can. Regarding an escrow, have not yet decided but i might require copies of winner's full identification for this particular coin if escrow is used.

really awesome
thinking of getting one

How does one "find" the private key inside if it is hidden without accidentally destroying the private key?

a slot is hidden inside, right beneath the precious gemstones, invert the coin and the high-grade stainless steel plates with engraved private keys(btc&eth) will slide out onto your palm. There's a little jingling sound of the plates if you shake the coin. :)

Item is up for auction: https://bitcointalk.org/index.php?topic=1568154.new#new (https://bitcointalk.org/index.php?topic=1568154.new#new)

Thanks for all the kind words,  :) this coin is special and given the current slow market sediments for physical coins now, but we will see how the offer goes..

Well, that is totally a new concept an I very much like it.

But in case I win the auction, will you be willing to load the 1BTC and 1ETH on the addresses I specify?

This is because I want to have it as a collector's item and will never plan on breaking the gems to reveal its private key.
So that way I can spend the money in case of emergency without touching the coin and losing its overall aesthetics.

It would appear not.

If you check the pictures, you will see addresses already engraved on the coin.

I assume these will be the ones loaded with funds.

The Ethereum side has already been funded with 1 ETH.

In that case, i can do another option of not funding the 1 BTC since coin is already funded with 1 ETH.




yes, the addresses are already engraved on the coin, for durability.

Okay that will suffice unless there is enough surge on Ethereum economy that I'll have to trade them off. :P
But anyways, that will help a lot. Thanks for accepting the offer. :)


You didn't quite understood my point.
I know the addresses are engraved. But I do not want to store the coins in those addresses as I do not intend to break the gems and reveal its private key in first place.

Rather, I want them being stored on a different address provided by me so that in case of emergencies I can spend the money without doing anything to the coin.

is that coin made from gold? wow its really interesting image that i ever see. one coin will have 2 both different face. i think it will be sold so expensive and will be precious coin in the world. and i think it will attract more people on the auction.

Gotcha :)

That is a great idea for something like this actually.

Personally, I have never peeled off a hologram and redeemed a coin.
Though I'll admit I have been close to doing so :D

I'd get this funded with the address on the coin.

But that's just me :)

ok can. :)




it's made from 999 silver, with gold and rhodium plating. Image taken from an iphone, this coin itself has many special attractions.

opened to pm offers.. Mintage: 1

Awesome coin!
Mind to tell the final price of this beauty?
I still didn't understand how can you sweep the private keys,I probably missed something.

well hey there Elias you still in China ?  I had no idea that was your coin :)  I found this place a couple weeks ago it was just what i needed. Hope your having fun over seas !

that says closed?
so did someone win or it was closed?

We decided that the auction was not the best way to go about with the sale.
If you are interested, PM me to make an offer. I'll arrange for shipping & secure transfer.

I'm based out of China right now, but am taking 2 months to travel in Asia  8)
I'm glad you like the coin!

Hey, hope you enjoy your short stay here in sg..

It is my pleasure to meet up with Elias, the author of encyclopedia of physical bitcoins and crypto-currencies. It has always been virtual in bitcointalk

for me, i didn't expect to actually meet up in person, he is currently travelling a round trip across in asia/southeast asia starting from china as i write

this post. Even got my booked signed(found its way back to meet its owner again temporary) personally  :o We chatted up, he explained/shared to

me about his book, what he's doing currently. etc.. I showed him the dual cryptocurrency.

Nice meeting you here Elias. :D I'm sure you have many stories to share too when you are back..

So basically, wheresmycoin ordered a First Print edition of my softcover back in April, but unfortunately, it never arrived.

So I did the obvious thing; I sent him a replacement and came to sign it myself!

World class customer service, if I do say so myself  ;)
