I present to you the most secure physical Bitcoin ever designed: The Double Universal.
It is Luxury. It is Power. It is Symbol.
The Double Universal has it all. 
The rim (
A) is normal, shiny gold, encircling the work of art. The outer rim has an unseen binary code spelling out “January 3rd, 2009”, the date of the Genesis Block. A matte gold base highlights the shiny raised Latin text, “Strength in Numbers”(
B), in between which is a number: Five. 5 BTC.(
C) Four arrows on the coin appear as those of a compass leading the way for universal adoption, but also hold a greater significance. This arrow containing the Bitcoin amount is the highest, pointing to the astronomical trend of it and other digital currencies, figuratively all the way up to the North Star. Contrasted with it is the downward arrow (
D), which has the text “2 ozt 999 Au”. Though having near equal value to its sky-high counterpart at the time of the coins inception, the arrow signifies the declining importance of gold in the future of wealth, pointing it back towards the ground from which it was dug out.
In the Center of the coin is a beautiful scene; the incorruptible bitcoin is shown amidst the Earth, Moon, and stars. To the left (
E), is an arrow as if a rewind button with the year ‘2009’. A small triangle symbolized the initial idea of, the completion of, and the presenting of the Bitcoin Whitepaper by Satoshi Nakamoto while the year signifies the beginning of the Bitcoin Era as the first block was mined. Next, one can imagine pressing the opposing fast-forward button (
F) to visit the year 2140 when the last block will be mined. The great Bitcoin transition will be complete, with all 21 million Bitcoin remaining for eternity as signified by the infinity symbol following the year.
Now we zoom out to view the entire face, where three major constellations each bearing seven stars poke out as intrusions to the mirror-like gold surface. They add up to 21, with each star symbolizing 1 million Bitcoins. As the stars, the incorruptible code will outlive this planet. As such the meaning of the lower text (
H) becomes apparent: Universal Currency.
On the BACK of the coin, you will find the standard information of year; hand engraved serial number, company name and ‘5 BITCOIN’ denomination, all separated by circuits to symbolize computers and mining which power Bitcoin. The hologram is where things start to get special:
The Hologram itself is the most secure ever created. It contains the popular safety feature of having a private key ‘window’, but it goes much farther than that. There are two more windows, showing both the Denomination AND serial number so they can be compared to those written on the coin. This takes away the possibility of someone somehow obtaining another hologram and using it. The hologram also features LASER RIMMING which has been utilized by Casascius and Lealana for some of the most premium coins. The Hologram features a prominent chain to symbolize the blockchain which holds everything together and protects private keys and balances within it.
Hologram colors: B is pure gold, and private key windows are gold-like. The area inside the Blockchain is mostly black, with gold sparkles and purple and red/yellow undertones. The Laser rimming is golden and blends in with the metal.
There is also an EASTER EGG under the hologram. If one redeems the coin they may find under hologram two circles of currency symbols. In the outer circles every major world currency; Dollar, Yen, Euro, Pound, Ruble is represented, and another circle with the signs of various alt-coins. A Bitcoin symbol reigns supreme in the middle. None compare with Bitcoin, and are buried underneath it's private key.
FRONT
Gold in text section is MATTE, with text being raised and POLISHED.
The face is POLISHED, with the B, Earth, and Moon in MATTE.
Compass arrows are POLISHED
BACK
POLISHED, except for raised MATTE letters and under the hologram for grip.
Presentation:
The coin will be presented in the standard Coinographic box, but with a twist! There will be a certificate card which will have an identical hologram attached in the middle, so as to make it visible when the box is open (so one can admire both the art and the hologram). The first bits are blank on the hologram, so it cannot be used for fraud. The denomination and serial number however are visible in the windows of the 2nd hologram, as to confirm the certificate belongs to the coin and is original. There is also a gold thread placed inside the hologram so it wraps around the card. For extra luxury, this could be replaced by a real gold chain!
In the box, the coin arrives in a classy black slab that can be opened by the buyer.
*There are many smaller features and prints that can be added to the hologram, but are impractical to do by hand. I envision much more smaller things in it in practice. I may also decide to change the binary text on the outer rim. also lastly; don't be stealing my ideas
