Hello, from time to time I see posts and also people selling on ebay chips they are claiming to be error chips. I was just curious if these are just from wore out dies. Any help would be great. The far left, and my pictures are not that great just has the wore out "E" which is appearing to be an "F". The other 2 Has the "F" and the lower part of the "D" is gone. Any help would be great. Thanks
