There are actually several different surface finishes / textures on Chipcos: Linen, recessed, satin, and slick.
This terminology comes from
http://chipguide.themogh.org/cg_faq.php - not everyone will use the same terms or describe the chips in the same way. But that chipguide page has some pictures, so you can compare the chips you have to their pictures and decide for yourself.
BR Pro / ABC Gifts and Awards ended up with a large supply of Chipco blanks; they were textured, I think with the "linen" finish. But their supply was running low recently, and I don't know if they still have any. You can send them an email and ask about them.
Other than that, I don't think there are any Chipco blanks still available, as Chipco went out of business a while ago. There was some discussion
in this thread that the Game On Chip Company (GOCC) might
potentially be still in business and might
potentially have some blanks that closely resemble the old Chipco blanks, but at this time that's really just wild speculation / wishing and hoping.
