Steve,
I also have green ones, that are not on either card. In fact the green one is the most common, I've seen.
I have not been able to tie Jake to the illegal ships. Allan thinks Katleman could be spelled wrong on the card. He thinks it could be the brother of (too early in the AM, can't remember the name) the guy that operated illegal games in Palm Springs and opened the El Rancho Vegas.

Here is the real kicker. Some green ones are overstamped (with a rubber ink pad stamp) Monte Carlo, which was an elite illegal CA gaming ship.
The MC went down in a storm before the brown chips were delivered.I have had long conversations with Ernie Marquez and have discounted this theory. HH can not find a card on the green chips.
Yes a true MYSTERY.
