The demo 1BTC coin is super rare. Its one of the very first Casascius coins made. Its mentioned in the Encylopedia in the following:

Quote

These are the first experimental coins made by Casascius. They were used to test the holograms to reveal the honeycomb pattern left behind, without ever being funded.

The coins can be identified by looking up the public key on a peeled, seemingly ‘pre-funded’ coin. If no BTC has ever been in the address, then it is possibly a demo coin. Currently, demo coins are only known to exist in brass 1 BTC form.

Casascius sold these coins to prior buyers as extras. On a few occasions, buyers who ordered Casascius coins had the option to also buy some ‘demo’ coins along with them.

While no numbers relating to these coins exist, it is no doubt that they are extremely rare compared to the mintages of normal Casascius coins. It has been suggested that these coins may be an effective way to invest in the collectable value of Casascius coins without exposure to BTC price fluctuations.

How many error coins are in existence? Any rough estimates?

According to the "Big Yellow Book":
**Not sure if this number includes S1 holos that were used for the Demo coins or Double Error coins**
There are 6109 of the S1 error 1btc 2011 coins
There are 677 of the S1 error 5btc coins
There are 345 of the S1 error 25 btc coins
There are 57 of the S1 error 100 btc bars
Some of the 1000 btc coins have an S1 error hologram..

So about a total of 7188 total Casascius items that have/had the S1 error hologram

Oh sorry I meant how many of the demo coins of lot 1 were produced and distributed
