Side note, I've got both normal and silver for Harris out of this set, and the Silver is actually larger than the normal, and does not fit a one-touch holder. I have to top-load it.
I've actually seen tonight where some folks put an empty sleeve on the face of the card after it's inserted into the base/cradle of a one-touch, and then the cover of the one-touch is put in place.
So it might act as a surface protector in that sense. Havent tried it myself.
It looks like I will settle for a 75-pt one, but I have purchased both a 75-pt and a 100-pt holders just recently. Thank you so much for all your helpful answers and links.
I actually might buy one size for each different thickness in the future just to try and see which one is best for different cards.
That's what I did, bought a heap of different holders (going back a few years now), and just tried them out. Then took note of which was which, and ordered more based on the needs for what cards I had.
Troubles these days, is there's so many different thickness's, it's hard to keep track.
