Thinking about getting a Cryptosteel (anyone experience using it?).
When you backup your seed, there is only space for the first four letters per word. Is the below quoted text applicable to Monero as well?

you only need to assemble the first 4 letters of each word. Those 4 letters are unique and sufficient to recover the sentence and the entire bitcoin wallet. We did a frequency analysis and determined the minimum set of letters that are needed [is four]

Monero seeds use the electrum wordlist.  The list was designed so that the first few letters uniquely define a word.
I heard it was actually three letters.  I'm not going to spend time searching for whether it's three or four.  
But here's a link to the wordlist
https://github.com/monero-project/monero/blob/master/src/mnemonics/english.h
Maybe you can use a script or spreadsheet, and compare the third letter in every consecutive word pair in that list.

I just did a quick visual scan of the third letter in a series of a few hundred of those words and didn't see any matches of the third letter in two consecutive words.

Thanks, will experiment a bit with it.

Noticed as well that the Monero wallet has 25 seed words, while the Cryptosteel has place for 24 words.

The last Monero word is a checksum, so if you know the first 24 you can easily calculate the last one. It might even work if you just try to import a 24 word seed, I'm not sure.

Edit: maybe not easily, but you can see the code for it here:
https://github.com/monero-project/monero/blob/master/src/mnemonics/electrum-words.cpp

The final checksum word is also a repetition of one of the other 24 words.  If you could figure out a nice strong way to mark one of the tiles you would know which word to repeat at the end.

Perhaps fingernail polish?  A sharpie pen? An engraving tool?

That is great news!

Just tried. Unfortunately the last checksum word is mandatory in the CLI wallet. The goods news it is one of the 24 words
And indeed it is an 'Electrum' seed.

Code:

monero-wallet-cli --restore-deterministic-wallet

Generating new wallet...
Specify Electrum seed: 24 words entered and skipped the last checksum word
Error: Electrum-style word list failed verification

just use a metal punch, whack the 1st char of that word.

You only need the first 3 letters of each word to restore the Monero seed, so there is more than enough space on a Cryptosteel.

That is worth knowing - I liked it until I realised it didn't have enough space for the full seed.  I ended up buying steel plates and letter punches, but I haven't got around to doing it - it's a lot of hassle.

I will look again at the Cryptosteel.

I think for Monero using English you only need the first three letters, but for other languages I believe you may need the first four.

And who knows in some future client. Id feel safer knowing the real phrase.

Let me apologize in advance for my n00b question here... beta GUI wallet has a December'ish date. If I use the monerod in the XMR beta gui I'm okay with the RingCT fork? Don't feel like downloading that for a week to find out I ended up on the wrong fork. I have the back end LMDB over nfs so it's going to take me a while...

No problem, and yep, you're good.

I have this error. Can anyone help me, please?

Not sounding good, sorry... https://bitcointalk.org/index.php?topic=652305.msg17256617#msg17256617

In other words, delete c:\programdata\bitmonero and resync the chain?

Looks like the Cryptosteel will let you insert the letters of the checksum word upside down.  If so, no permanent modification is necessary.

Of course I keep my HD seed hidden in a tattoo on my scalp!

Found this pic on the Monero subreddit.

It's really good.  A few more improvements will completely fix it.

1. Replace Transportable with (or add) a Digital category for BTC, XMR, and fiat.  Only giant stone Yap coins are not transportable, so it's moot.

1a. If leaving Transportable in, at least make the dollar faded (or cut the pic in half) to indicate the issues with moving non-trivial quantities of them.

2. Add Silver, indicate it is not Non-consumable (most is used for industry and not recovered).

3. Gold and Silver are fairly Divisible, more or less.  Bengals in South Asia, plus many denominations of gold coins throughout history.  Pieces of eight were like the Age of Exploration's Valcambi bars.   

4. Instead of (or in addition to) using the subtle faded icons for a weak property, cut the icons in half.  It's much easier to notice and intuitive for a semi-held property.

5. Change the shell pic to Nassarius gibbosulus and indicate monetized shells are both Scarce and Fungible.

Per the long-awaited sequel to the classic Shelling Out essay,

These people walked the shore not just in search of food, but also in search of a very specific set of uncommon yet authoritative objects – shells of the sea snail Nassarius gibbosulus. Once collected they were selected for size and intactness, and laboriously perforated.

Upper Paleolithic shell bead manufacturers were very selective of which size and shape of shells they chose to turn into beads: the resulting beads had “great consistency…of size and shape” compared to the natural biotic distribution of the shells.  Most variation in shell species, shape, and size was eliminated during manufacture. They were as similar in size, shape, and weight as it was possible for a collectable set of natural objects in that environment to be.

I want to try out the GUI, so the first three people to remake the image (.png please; we are not savages) with the above improvements gets 1 shiny new Monero.

Best version (my choice) gets a 1 XMR bonus.

Found this pic on the Monero subreddit....

Nice, but why is gold only partially fungible? I think any element is 100% fungible correct?

Good question.

Here in the real world, gold is only semi-fungible because:

A. Bullion contains a fingerprint of radioisotopes and trace minerals that betrays its origin.  No bullion is 100% pure.  And 100% purity would function as an identifying characteristic.

B. Larger bars often have a serial number.

C. The possibility of/propensity for whitelisting is non-trivial, because there is a movement akin to the "ZOMG Blood Diamonds" social justice bullshit which seeks to curtail the market's supply of non-kosher "conflict minerals."

D. The particular form factor of gold bullion is not trivially alterable and alterations (IE smelting/refining/repouring) incur thermodynamic and transactional/economic friction.  Even in nature, gold nuggets are unique.

Perhaps the best illustration of this is when you try to sell 1oz of gold to your local coin store, and the price depends on whether that 1oz is in the form of an American Gold Eagle, Panda, Maple/Brit/Philly, generic round, shot, or 14k jewelery.

In contrast, the price of 1 XMR is always the same whether it was mined by a Chinese botnet and previously used to pay Hillary's friends in ISIS or freshly mined by Fluffypony and never previously transferred, because there's no way to tell the difference.
