I got an M-disk drive from Amazon using spendbitcoins.com.This is supposed to use a high power laser to etch the data into special rock-like DVDs .It should last a long time. The DVDs are readable by any conventional drive.

Lasers are awesome!

I could see using one of those army "dog tags".

As long as you can find someone who will use mixed case... or possible find a vanity address generator that can enforce all caps?
I just came across brainwallet.org.
It has a convert tool that can output a key in RFC1751 format.
This is all upper case like this,

5JbrP892xZEXW9ZAyxaspYYW1qUYk4epi1E5qrVuyo18LET7Zgv equals
Code:
CLAW LOOT QUO FANG BLED GEL GWEN BIND OFF
CLOD REST HUNK SAM BOSE DUET ARMY KIT OK
MOOT SOUL LUND TIDE BOUT KLAN
Unfortunately it's 112 chars and according to the dog tag offer they can do 5x15 = 75 char only.
So two tags would be needed, as offered for $4.99. Which isn't a bad idea anyway. Keep them in two places and bring them together when needed.

Or use hex - but upper case, only 64 chars =>
Code:
67764CD7BEE5902
D91CB04BAB3DCE

I would want to make it myself, you never know if they keep a copy of your work order somewhere.

You could just get an alphabet metal punch set and put the key in manually.

i actually have the equipment to do this on hand. i personally prefer using brass to copper - but really i could use any electrically conductive metal. i use galvanic etching (salt water and electricity instead of acid) and then after removing the ink resist a blast of black spary paint really makes the design pop. a simple spray of clear varnish is excellent protection.

if there's enough interest i'd be more then happy to offer a service. i feel stupid for not thinking of this before, actually. Cheesy

here's an example of the etching: this is about the size of half a sheet of regular (8.5x11 or A4) paper. all the "blemishes" you see are there for intentional artistic effect.

The image of all the "copper" coins looking "shitty" earlier is a joke. Firstly, those are not copper coins, they are Zinc coins with trace elements of copper. Also these are coins in circulation not a private wallet. Lastly, you allude to using Gold which is a softer metal typically made stronger by ADDING COPPER to it:

Pure gold is too soft for day-to-day monetary use and is typically hardened by alloying with copper, silver or other base metals

Bullshit. Pre-1983 pennies are 95% copper alloy. Post-1983 are copper-plated zinc coins. Plated with pure copper.
Other posts in this thread have actually convinced me that corrosion might not be a problem, but the post above only convinced me that Dunning-Kruger effect is endemic in this forum.
