Here are scans of the front and back. The chip on the left has no denomination and is a lite green. I already have the lite green (2) and I'd like to get the other two chips. I was supposed to get these chips from another member but I lost all the contact information for this gentleman and cannot remember his name.

As far as the chip looking painted, it looks that way to me as well but without actually seeing it, I cannot say. I have a couple of chips which have lost luster and have experimented (with chips in BAD shape and virtually worthless) in "luster restoration" so it's hard to say what the deal is with this chip but even my experiments don't look anything like this. It looks almost plastic or coated pretty good with something!

I'm really hoping to find the other Brown's chips but large crown chips, illegals or crest & seal chips would be considered for trades as well.
LMK. I might not respond today as I'll be on a LONG motorcycle ride through the Texas hill country. Also, info on a newer price guide would be appreciated.
