I just went through my desk and found all of mine, the problem is they don't fit on the cable ring I have on my backpack. For the old plastic ones I can flex it a bit and get them on there, but the diamond ones are not going on. I guess I could use the cable delta sends but I just opened that package and it's an obviously crappier cable.
Anyway, I found a bunch of old platinum and gold tags, and I found my old silver membership cards but I couldn't find any silver tags.

I could just get a hole punch and add all my hotel and grocery store cards on there as well I suppose.
