I'm confused. Not the first time and not the last, but maybe someone can help me out.....?

During the last great Convention, I, like many others, picked up the $5 Las Vegas Thunderbird issue offered by Nevadamint (Rene, Richard and Steve (at that time)). Today, while going through the Illinois Illegals at the CHIPGUIDE.com, I found a listing for a Thunderbird. Several chips were identified, including the same $5 Thunderbird (but drilled). As the first several chips of this Illinois Thunderbird stated that they were not "confirmed", I was curious why such a disclaimer is not used for the $5 chip.

Is is a Thunderbird Illinois chip? I know that no one confirms that it is a Thunderbird Las Vegas chip, but does this rule out that possibility?

Enquiring minds want to know. BTW-Scan is courtesy of the CHIPGUIDE.com. Use link below to go there.
