Proudly announcing zinc alloy tokens with the "Segments" Design concept

The tokens have a similar design concept like my "X - Series Segemts" which can be found here: https://bitcointalk.org/index.php?topic=1746500.0

This series has 6 finishes and come either DIY or preassembled.

Specifications

• Zinc alloy with various plating options
• 31mm diameter
• Serialized - 100 of each finish

These coins will come in the following six variants/finishes:

• Satin Black
• Gold
• Silver
• Partly gold
• Rose gold
• 24k Gold

Pricing

• DIY: 0.0075BTC
• Preassembled: 0.01BTC

Shipping

• EU: 0.003BTC in envelope untracked | 0.005BTC package untracked - 0.008 BTC package tracked
• US: 0.005BTC in envelope untracked | 0.01 package tracked)

With orders along my X-Series coin the shipping will be free.

AssemblyIf the coins should be preassembled they will be assembled using a hologram which shows the firstbits using a "window" and the serial number will be shown on the hologram itself. DIY holograms do not have a window nor does it have serials.

The preassembled addresses will be in this format: 1TXXX
XXX - serial number of the coin e.g oo1,o17, o99, 1oo (0 has been replaced by o due to address character restrictions)

Delivery scheduleThe coins are ready to be assembled and shipped.

Pictures (will be updated with better ones)






Reserve NOW:Reservations are open for these coin from serials 01-100 for each finish. People who have reserved one of my X-Series coins will have priority of reserve for the serials of their reserved X-Series coins. (Only applies if the person has reserved a set of 3 or 2 coins).

[Starting bid: 0.00 BTCBid increments: 0.01 BTCEnding time: 13th January 2017, 6pm GMT (default forum time)]

Because the coins are still being minted I have the ability to engrave your name instead of a serial number onto the coin. This is the only set being sold, no more than 4 of these will ever exist (one will be owned by me). Giving you the opportunity to own a unique and personal set of these shiny coins.

You are bidding in order to have your name/message of one word engraved onto one set containing a plain silver, a partly gold plated and a fully gold plated coin, winning bid does NOT include the purchase price of 0.75 BTC (including funding) of the coins. Each coin can have a different word. More information about the coin can be found here: https://bitcointalk.org/index.php?topic=1746500.0

Starting bid: 0.00 BTC
Bid increments: 0.01 BTC
Ending time: 13th January 2017, 6pm GMT (default forum time)

The reason for an early auction like this is that the mint needs to know what exactly to engrave as soon as possible.

Don't miss the opportunity to have your own customized coin set! I do not encourage sales of these personal sets, it should be something special only owned by you.

The coins will be assembled and shipped out in February.

Because of all the mess that was going on with my reservation thread here: https://bitcointalk.org/index.php?topic=1747532.0 TMAN actually decided to let go of one of his fully gold plated one go as a charity auction.

100% of the auctioned money will be going to the charity organization of the winner's wish. Tracked worldwide shipping will be provided by me.

Note that every purchase comes with a DIY token, details are soon to be announced.

[Proudly announcing the first coin of the upcoming X-Series: Segments]

Proudly announcing the first coin of the upcoming X-Series: Segments

After almost half a year of work, I'm glad to announce my first coin. The first coin of the X-Series will have the iconic "X" as the main design element along with segmented "spikes" representing the rise and drop of bitcoin. A one of a kind coin in the market.

There will be many more variations of this series to come.

Specifications

• 1 troy ounce 0.999 silver
• 40mm diameter
• Preloaded with 0.1 Bitcoins(only the full golden one)

These coins will come in the following three variants:

• Plain silver - only 25 serial numbered for sale

• Partly 24k gold plated - only 25 serial numbered for sale

• Full 24k gold plated - only 10 serial numbered for sale

Pricing

• Plain silver: 0.1BTC
• Full 24k gold plated: 0.2BTC

All prices include funding. ONLY the full gold variant will be funded, the other two will only come preassembled.

Shipping

• EU: Free (tracked)
• US: Free (untracked)

Tracked shipment to the US will cost an additional 0.02 BTC. Other shipping couriers or wishes can be discussed individually.

Vanity addressesAll the coins will be delivered with a vanity address which is generated according to type and serial number. If you have a coin that has a "0" as serial number it will be replaced with a "o", because of character restrictions.

Some examples:

• The silver coin with the serial #1 from the first X-Series will start with "1X1Ago1"
• The silver coin with the serial #10 from the first X-Series will start with "1X1Ag1o"
• The silver coin with the serial #22 from the first X-Series will start with "1X1Ag22"
• The partly gold plated coin with the serial #22 from the first X-Series will start with "1X1GP22"
• The full gold plated coin with the serial #10 from the first X-Series will start with "1X1Au10"

These addresses will be generated using a fully offline and custom Linux USB drive, then encrypted and exported to an old mac, which will be formatted and used solely for printing these keys through a laser printer. All of this will be done fully offline. The USB will be destroyed upon successful export (burned?). These printed keys will be sprayed with an "Aerospray" to ensure that the keys will be readable after centuries.

Delivery scheduleThese coins are currently being minted, so please keep this in mind. I expect to be able to ship to everyone by the end of February, but this is an estimate. This thread will be updated accordingly along with pictures of the coins final version and a picture of the created holograms.

ExtrasA FREE DIY token will come along each coin purchase! I'll create a separate thread for those. All coins will come in an airtite capsule and will be enclosed in a small Xerola box. By request the box can be replaced with a velvet pouch.

UPDATE: Winner announcement: https://bitcointalk.org/index.php?topic=1735156.msg17451737#msg17451737

The bounty:
0.5 BTC for the winner + 1 0.999 silver coin to be released soon
All other participants get a to be released brass token
(shipping included in the EU, about 3-5$ for shipping elsewhere in an untracked letter)

Requirements:
A self designed TWO TONE hologram (2 layered)
The hologram needs to be 25mm in diameter
There should be a cutout in the very center to show the firstbits of an address (about 8mm in width and 3mm in height, the addresses will be printed on a 1cmx1cm circle)
"XEROLA" should be added to the design element
The hologram design should be done in Adobe Illustrator or converted to an .ai file. PSD is also accepted.
(The fireeye (my avatar) can be used too, but should look good and placed correctly )
(A rendering of the hologram is very helpful)

What determines a good and a bad design?
A good design has a geometrically symmetrical design concept. There should be design elements such as waves or other patterns that "decorate"  the hologram and make it stand our of all other holograms.
A bad design is just pasting bitcoin logos and a few shapes into a circle with no concept and/or design knowledge. It won't get you a brass token.

You can take existing holograms as an inspiration, but you shouldn't copy paste the design. A few examples of good holograms are the casascius holograms, crypto Imperator holograms, microsoul holograms... Maybe have a look into them before you start working.

When will the winner get announced?
The winner will be picked and announced by me on the 15th of January 10th of January. Deadline for submission is 9th January 18:00 GMT. The winner must send me the .ai file before the payment is sent.

Good luck!

Hello,

I'm currently buying 100 casascius aluminum coins, shipped to Austria. Please leave me an offer
BTW, are these still available on the casascius official website? There is an option to buy it, but casascius has been inactive recently, that's why I'm asking.

Kind regards,
Zeroxal

I'm looking forward to buying 25 Satori coins. Please PM me with your price, including shipping to Austria.

Thanks

[Presenting you project XEROLA.]

Presenting you project XEROLA.
I aim to bring new series of coins into the physical collectible bitcoin market by introducing whole new designs with a modern touch.
Because this will be the first ever physical bitcoin I'll will make and sell, I kindly ask you for opinions.

What will the mintage be?
No more than 100 coins will be minted for each design. Each design will consist of 50 preloaded high quality .999 silver coin and 50 more affordable unloaded or DIY version of the coin (plated zinc alloy or brass).

What's the goal?
The absolute highest priority is quality and uniqueness. Every coin will be engraved with their unique serial number and encapsulated immediately after the minting process. An unique hologram for each year will be placed onto the back of the coin, covering and protecting the private and public key. The public key will be shown through a small transparent "window" in the center of the hologram. My goal is to make a series of coins that will suit everybody while being innovative at the same time.

Why should this coin be so special?
The packaging will contain the following:
1x Unique PGP signed certificate of authenticy
1x Xerola branded Velvet pouch
1x Airtite Coin capsule
...and many more to come along with the coin announcement.

To make the project more original and stand out of the crowd, the whole packaging of the coin and and COA will be sealed using an unique seal that hasn't been seen on the market ever before which looks absolutely beautiful. It will be revealed along with the first coin.
Each coin will have a securely generated vanity address that will relate to the series, material and serial number. For example a "X" series coin made out of silver with the serial number 1 will have a public address starting with: 1XS001

What will the design look like?
Serveral designs have been created by me and I decided to show one of them for you to judge
The "X" Coin (X because of Xerola):

Either gold highlighted or pure silver.
(Note that this is only a design concept and the final design will probably be retouched to fully suit the coin)
Due to the first coin ever being made by me, the nomination will likely be changed to 0.01 or 0.05 BTC.

Edit: Design concept number 2:

This was originally planned to be released as a bitcoin token with no face value (similar to bitcoin penny). Let me know your thoughts on this design. Should it be released as a token or a funded coin?
3d renderings of design 1:



How do you ensure security of the private keys?
Now comes the part that frustrates me the most. Because I will be selling prefunded coins with a private key generated and printed by me, I want to ensure that none of the prefunded coins will be unloaded by a third party or even me.
To ensure printing and generating security, the vanity addresses will be generated on a Macbook with a freshly installed operating system. These keys will then be combined into a print document which will be printed on an offline printer directly connected to the Macbook. The whole process will be done offline.
After printing, the private key files will be destructed and the public key file will be kept in order to fund the coins. That being said, it's up to the buyer to trust me on not keeping any private key info.

Pricing:
1 Troy ounce .999 silver coins will cost around 0.15-0.3 BTC/each (excluding funding amount)
Plated coins will cost around: 0.03-0.08BTC each.
Prices may vary on the bitcoin market price of coin launch.

Please give suggestions!
I'm not sure yet if the coins should be prefunded, therefore I kindly ask you to give me some suggestions by voting on the poll.
All suggestions and opinions are very appreciated!

It isn't confirmed yet if any coins will launch. But they most probably will when there is enough interest in them
(I know this thread is a little messed up, I'll put more effort in it and edit it when I'll have time)

Because of the casascius vs money transfer law incident, I wanted to ask if there are any laws in Europe that are similar to those in the USA. Would a sale of self created physical bitcoins with 10BTC loaded onto them in total need to be licensed?
