First, I was not clear in my posting. I made the mistake of not saying that the 2 varieties in TCR are of the $5 chip without serifs. Including those with serifs there are 5 varieties in my TCR. One of the varieties I have (without serifs) has a "fat H", the other 3 have thinner "H's", but the "s" at the end appear to be different. I was hopeing someone had some info on this.
