particular chip, suggest that you make sure that you know that there are thousands of them available, that vast majority of which were hot-stamp cancelled on one side. And of the cancelled thousands, many of thos had the hot-stamps removed.

So, you might want to clarify, do you want 5 that were never cancelled, 5 that were cancelled and the hot-stamp is still intact or 5 that were cancelled and the hot-stamps were removed?

This is what the hot-stamp looks like. Evidently, it was not deeply impressed into the chips and was fairly simple to remove with some elbow grease and a some sort of checmical. I can't recall specifically, but lighter fluid or Goof-Off (Goo Gone) come to mind.

The cancelled versions are in abundance over on ChipTalk.net.
