This Dexter Saloon chip in this auction appears to be a fake. Look at the way the linear pattern runs through what should be a hot stamp from over 100 years ago.
The same type of fakes were made for the Lusitania set... pictured as well. Look how the text runs down the angled edge of the chip. I believe these were all made with a laser engraver.

There are also a couple known Cuban chips that were made the same way.
