I think this was the first physical Bitcoin ever produced. It's described as an "error" in the ebay listing, but there is no explanation of what the error is. More importantly, there is no clue about what the non-error type is - and we would need to enter both types, if they exist. Sometimes types are errors, but there were no non-error types minted. The new type(s) should go in CCT7214: Casascius Bitcoin. I propose the new type name should be 2011 brass Bitcoin Casascius 1 BTC error.
Please confirm.
These were the first physical Bitcoins ever produced. Started by Mike Caldwell, this coin is referred to as the 1 BTC Casascius Series 1 2011 'Error' coin. The error is the spelling of 'CASACIUS' in the small hologram text on the middle left and right of the coin.

The non-error version of this coin is known as Casascius 2011 Series 2. There are two main differences, the correction in the spelling on the hologram, and two, rather than printing the visible portion of the public key on the hologram itself, a small window is cut to show the first digits of the public address. This was done as a result of a potential security gap with the Series 1 coins and is how all Casascius holograms were made moving forward.
Thank you for that excellent information. It attempts to describe 10 different types, of which they succeed in verbalizing only "two special varieties" and 1 "new version". I have much more clearly defined the types below, with our renaissance numismatic methods. Hopefully the utility of the Coin Compendium and the importance of CC project will be much more apparent to cryptocoin collectors:
*
2011 6.8 g brass Bitcoin Casascius 1 BTC, mintage 7749 or 7753.
*
2011 6.8 g brass Bitcoin Casascius 1 BTC version 1, mintage 6105 or 6109. Alternative type name:
2011 6.8 g brass Bitcoin Casascius 1 BTC series 1 (it's not a series).

The errors in the 2 book pages are:
* Coins are "sought after" due to popularity, not "perception of rarity". "Perception of rarity" is a misunderstanding of fundamental of popularity. I call this Warren Esty's Law. I like "Warren's Law" too.
* 2 different mintage figures are given for the
2011 6.8 g brass Bitcoin Casascius 1 BTC CASCACIUS error funded in 2012, 1574 in the text, and 1578 in the mintage table.
Surprisingly, the authors correctly pegged "PF" as a type - NOT A GRADE! They used "MS" as a grade, which is more or less correct. It's clear the authors have good intuition about some of these basic numismatic concepts that have been lost or misunderstood during the numismatic dark age. That said, "PF" means "proof", which is normally meant for examination for quality or for collectors, but these coins were unambiguously intended for circulation. "MS" means "Mint State", and it, along with "BU" or "Brilliant Uncirculated", are adjectival grades that are often misunderstood and misused to mean "not proof" or "intended for circulation".
Please check my types and data above for errors, and once confirmed I will enter the data myself, and then we can start seriously tracking market data about these coins.
