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?

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)
