I can weigh some top loaders and cards when I'm home, but my scale is terrible and rounds to the nearest 2 grams, so if anyone has one that's more accurate, feel free to post your results.
I did some searching online though and found this:
a single card weighs 0.064 ounces (1.814 grams).[67]
Then I also found this information:

I'm thinking that a 000 mailer, top loader and 4 cards comes out to just over an ounce, but that's off the top of my head. Keep in mind you'll be adding tape and a label to the outside most likely as well.
edit: So I weighed some things. I got 3/8 oz for just a #000 envelope with a label. So I started piling on cards and top loaders and stopped when I hit 2 3/4 Oz. This was at 19 cards 12 sleeves (various brand) and 3 toploaders. So you can fit quite a bit in a bubble mailer for under 3 oz.
