I have all 3, 5-25-100, all drilled like yours. They are genuine. As Chuck said, if it wasn't drilled you may have to be concerned, as Dave Whelan has reprocessed some of the drilled ones to appear to be undrilled. For this reason, I consider the drilled ones to be just as valuable as the undrilled. This is the consequence of the process of altering chips. It makes even the unaltered or undrilled ones, questionable. DO NOT HAVE CHIPS ALTERED!!!
