I had one in my collection and one in my trader book which I am now updating. So after reading your posts I decided to look at them with my UV light. Thanks now I haven't decided what to do.

One chip has a small H&C below the 25 on both sides. The other chip has a larger H&C actually under the 25 on each side. For now I will put them aside and make a decison later if I want both.

Remind me to give you a kick when I see you.
