The $1 chip is in TCR rated "H".
I am told they are on ebay.
I also have it from a very good source that 700 of them have been found. That should make it close to a $3 chip.

Just information.

Geez, I hope they didn't find a bunch of the $25, also. I got mine for $25. I did know know it had gone up to a "Z" chip.
