Most, but not all, of "the Borland's" have a thicker, darker hot stamp, almost copper in color. This one looks similar to one of mine that I know to be authentic. This one of mine is not coin nor medal aligned. The hot stamp is very fine and a light brass in color. I have seen some from the Silver Slipper and the Castaways, that are difficult to tell.

This is the main reason that altering and counterfeiting chips is wrong and detrimental to the hobby. There is always scepticism present when viewing these chips and even the good ones become tainted. This even pertains to the so-called, rare chips, that have had inlays replaced by Whelan or others. How can any chip be called "rare" when there may be many more fakes out there, that we can't tell the difference betwen the authentic and the altered ones? David and the persons who have had chips altered by him, have sure messed up a good hobby!
