I have and only know of what you show. Of course, I have many variations of them, and many colors.

Here is the only really different one, in the same style of the other old embossed numerals -- a $1.00 one. You can have one for $7 total.

Can you see it well enough? The chip is jet black. I used a lot of "brightness" on my picture editing thing to get it to be seen in some detail. If I didn't do that, it would look like a plain black chip.

Another approach I just learned recently to see the details of very dark pictures, and it works on your picture: I "select ("highlight"/ type command-A) the picture (or the whole page) and find that it is much easier to see the details by doing that.
