I ended up with what I expected to be a duplicate of the $2 from Seabrook. As always, I pulled out the black light for a glance and saw that one of them has an inlay that glows under UV and the other one didn't.

I only have one of the $1 chips, and that inlay doesn't glow, but who knows, there may well be glowing versions of the $1 as well. So please, check your Seabrook $1 chips under a black light and let me know if you have any with glowing inlays.

If you have dupes, I would like to buy or trade for one. Thanks!
