I need to play catch-up here...
Sorry, had a long day yesterday! Just over 14 hours at work and by the time I got home last night, I was dead tired and went to bed. I'll look at my $1's tonight, which I got about 3 weeks ago and thought they all had repeating "Wynn" across the inlays. But, these are probably a re-order and may be different than the initial order. Since I have examples of both, I'll check it out and post the results. But now that you mention it, I seem to recall that the original order of $1's did not have UV tagging.
It's probably in the Archives somewhere, around the time the Wynn opened.
